Information about the STEREO (NASA) mission. Live images of the sun A at this time
STEREO (Solar TERrestrial RElations Observatory) is a NASA mission to study solar activity. Two identical spacecraft were launched on October 26, 2006 into orbits close to the Earth's orbit around the Sun. During the project, one of them gradually lags behind the Earth (Behind), and the other, on the contrary, overtakes it (Ahead). This makes it possible to simultaneously observe the Sun from two different points, i.e. use the stereoscopic effect, which makes it possible to obtain 3-dimensional images of structures and phenomena on the Sun.
When the Stereo satellites were launched, they were supposed to move in front of and behind the Earth at a given speed, which would allow them to increase the angle by 45 degrees each year (in front of and behind the Earth), meanwhile keeping the Earth in the center (according to reports on the Internet, the nature Stereo probes are moving so that they gradually "diverge" in the orbit of the Earth. The goal is to achieve an angle between the radius vectors of the probes of 180 degrees. This will allow scientists to observe the entire surface of the Sun. The required angle will be reached in February 2011). So they told the public, but these satellites were launched not in order to explore the Sun, but instead they were intended to explore Planet X. The satellites were launched in late October 2006 and were moving in different directions at a speed of 22.5 degrees per year, which led to the fact that by the end of October 2010, the Stereo satellites were located almost opposite each other.
It is known that the appearance of Planet X and its surrounding components is different from the view of any planets captured on images of the SOHO or Stereo satellites. The planets are balls reflecting light directly, while the body of Planet X most often appears as a cross or Winged Disk with a drifting tail. The Moon Swirls of Planet X are seen as long streaks or look like a tick or a String of Pearls again with a drifting tail. Therefore, the appearance of the body of Planet X may be confused with one of its Moon Swirls. What is it about a recent image of the Rear Stereo satellite that looks like a moving multi-beam cross? If we take into account real the position of the Stereo satellites relative to Earth, it can be seen that this could indeed be the filmed body of Planet X, which it is! 
Below is a rear satellite image of the Stereo Behind H1 from November 2nd, 2010. 
Planet X should have appeared in the Stereo Behind image to the right of the Sun, but there are several reasons why it is there one day, then absent the next, and then reappears. NASA is not interested in observing the Sun, any comets, stars or constellations with its stereo satellites. They are interested in triangulating the Planet X complex between two stereo satellites and any other satellites receiving data on the direction of the Planet X complex. Planet X should have appeared in the Stereo Behind image to the right of the Sun, but there are several reasons why it is there on one day, then on the other is absent, and then reappears. 
Why does Planet X appear on one day, as it did on November 8th, 2010, but was not there a few days before on November 2nd, 2010? Just as the Second Sun appears on Earth on occasion when sunlight bounces off the massive dust cloud surrounding Planet X at the right angle, the appearance on the Stereo Behind satellite cameras depends only on the right angle of reflection of the sunlight. What is seen now cannot last long. But this not means Planet X is out of sight!
Other cameras on the Stereo satellites also capture Planet X:
The satellites or moons of Planet X travel like a necklace of pearls behind the monster of the wandering planet, as they have been captured by its gravitational field. It has also captured a lot of debris ranging in size from boulders to gravel, which stretches far behind like the tail of a giant comet. They first showed up in late 2003/early 2004, when Planet X had already entered the solar system, slowing as it approached the Sun, and its tail was extending past the Earth. The tail then skidded past Planet X towards Earth.
Planet X has a couple of dozen moons, and they form into seven moon swirls that become tubes as they rotate relative to each other, and look like tubes from the side. Since sunlight enters through these tubes, they can appear from the front like bright balls in the sky, because the light captured and focused by them is directed by the inside of these tubes in a straight line.
Literally in a flurry, one after another, the phenomena of the Pearly String appear on the images from the COR2 camera of the Stereo Ahead satellite. 
The tail of Planet X is made up of several dozen large moons and countless smaller moons, lots of debris and charged red dust. Depending on the angle, sunlight can sparkle off part of the dust cloud surrounding the Moon Swirl, so it can look like drifting tails of light. Or it can sparkle, reflecting off the single moons in a string, each surrounded by its own cloud of dust, making them look like a String of Pearls. During the last weeks, when the Planet X complex is close enough to be visible to humans, many of these moons will be visible in their moon swirls, seen as tiny dots.
Moon Swirls can be at a distance or be near. Therefore, what appears in the images of the Front and Rear Stereo Satellites is not close to or near the Sun, as one might assume. There are also dominant and submissive moons in the strings. The dominant moon is often a large moon, loosely positioned at the head of the string, while others vie for position.
This is another example of observing Moon Swirls as a String of Pearl phenomenon. The L-shape, sometimes with extra lines radiating from the central connection point, is due to small swirls coming from a single large moon. These whirlwinds originate within a charged dust cloud and when their charge is different they tend to separate from each other like your statically charged hair does, standing up and moving apart. 
In February 2010, the internet was buzzing with imagesof the forward Stereo satellite, showing Earth-sized objects believed to be orbiting and close to the Sun.
It has been suggested that these objects were orbiting the Sun, since the traditional trajectories are considered to be the circular motion or the trajectory of a comet slowly flying past the Sun. And what else? NASA's stereo tracking areas overlap, capturing space in front of the Sun, which is where Planet X is currently located, moving slightly to the right of the Sun as viewed from Earth. Therefore, the body of Planet X appears on the Forward Stereo Satellite images on rare occasions. But Moon Swirls can travel a long distance from the body of Planet X as they drift out of the magnetic N Pole of Planet X and get caught in the turmoil of colliding magnetic fields, and so can traverse the areas seen by the Stereo Satellite's camera. They were the ones that were observed. These moons of Planet X are not the size of the Earth, although many are larger than the Earth's Moon.
In the image, one of the moons of Planet X shows a clear blunder in NASA's image retouching program. Since pathetic attempts to explain the object as if it were the same Mercury left over from the previous day are unlikely to impress ordinary people, in the minds of many of whom the suspicion has settled that between the Earth and the Sun there is some objects. When Planet X was continuously in the same position, the program usually erased what was there and replaced it with the expected backdrop of stars. This practice was complicated by prominences from the Sun and passing planets, but they could be expected and programmed. But when there is too much activity, errors occur. There are videos on YouTube that show the transit of Saturn, then it disappears and then its transit is visible again. This is an obvious retouching job, and it horrified NASA workers. There is too much movement going on right now, due to the repositioning of the satellites and the Earth and Planet X, that it appears in random, different places.
And here is the picture where Planet X was registered left.
Could the Stereo Ahead satellite have gone far enough in Earth orbit in just a week for it to appear on the right? Looking at the images from the Stereo Ahead satellite for the date December 7, 2010, it can be seen that the flare is rapidly moving from right to left. Consider the position of the Earth and Planet X relative to the Stereo satellites shown in the figure. The huge tail of Planet X can stretch for miles, and if Planet X itself can catch a glimmer of sunlight and bounce it back to the Stereo Ahead satellite, so can a large mass of matter from the huge tail of Planet X. This is what was captured, and NASA trying to hide it.

On August 21, 2016, NASA engineers managed to restore communication with the STEREO-B spacecraft, one of two STEREO (Solar TERrestrial RElations Observatory) observatories to study solar activity.
The STEREO-B observatory last contacted on October 1, 2014, after which contact was lost. For 22 months, NASA specialists tried to save the device - and they still succeeded!
Another attempt to establish contact with the lost device was carried out through the NASA Deep Space Network (DSN), an international network of radio telescopes that is used for radio astronomy research and for controlling interplanetary spacecraft. This time the attempt was successful.

On August 21, 2016 at 18:27 EDT, the DSN set focus to the downlink beam from STEREO-B. For several hours, the signal was analyzed by Mission Operations specialists to establish the coordinates of the spacecraft. After that, they remotely turned off the high voltage transmitter to conserve battery power.
Now that the STEREO-B coordinates are known, engineers can turn the transmitter back on remotely at any time. They plan to do this in the near future in order to continue the process of restoring the satellite to serviceability, regaining control over its movement, assessing the performance and checking the functional readiness of all subsystems and scientific instruments.

Solar observatories STEREO-A and STEREO-B are supposed to shoot the Sun from unusual angles. For example, on the opposite side of the Earth. Thus, for the first time, scientists were able to photograph the Sun from all sides at the same time. One of the devices gradually lags behind the Earth (Behind - B), and the other, on the contrary, overtakes it (Ahead - A). Due to this, it is possible to simultaneously observe the Sun from two different points and create three-dimensional images.
It was the specific orbit of the STEREO spacecraft that caused communication interference. Due to the slow drift relative to the Earth, at some point in time, each of the devices went behind the Sun, that is, to the opposite point of the orbit from the Earth. At this time, radio communication with him was interrupted for three months due to interference.
The two STEREO spacecraft were launched in October 2006, with a two-year life expectancy. As is often the case with NASA spacecraft, they were able to operate much longer than planned. When scientists realized that the devices could go into the interference zone behind the Sun, and then get out of there and continue working longer than planned, they began to plan this operation.
Each of the devices was equipped with a hardware communication loss timer, programmed to automatically reboot the systems if no commands from the Earth were received within 72 hours. Such a timer was implemented to automatically correct problems that could cause a loss of communication. This means that, having gone behind the Sun, the device rebooted every 72 hours, after that it corrected its orbit according to the stars, directed the antenna to the Earth - and continued to try to get in touch. Having gone behind the Sun, the device had to do such reboots for three months. Therefore, NASA engineers pre-tested the performance of both devices after the reboot, specifically silencing communication with them for 72 hours.
STEREO-A successfully passed the test, but its twin STEREO-B, after muting the connection and a forced reboot on October 1, 2014, for some reason, did not get in touch after the prescribed 72 hours and 20 minutes. He was unable to correctly point the antenna to Earth. From a weak and fragmentary signal, the engineers determined that an unexpected failure had occurred in the Inertial Measurement Unit, which determines the rotation speed. This module gave incorrect information to the computer guidance and control system of the device - and reported rotation even when the device was in a static position. Because of this, the antenna could not aim at the Earth. Worse, due to incorrect information about the rotation, the device could turn the solar panels the wrong way and partially lose energy. Worse yet, the control computer might decide to engage the motors to eliminate the vehicle's rotation. Since in fact there was no rotation, after such a correction it could really begin.
The specialists tried to send a command to the STEREO-B control computer to ignore the readings from the failed IMU, but the connection with the device was already lost.
STEREO-A continued to work normally, coming out from behind the Sun, but it was no longer possible to get stereo pairs of photographs from two observatories.
Engineers have yet to find out the exact cause of the malfunction, but the main thing is that now communication with STEREO-B has been restored. Solar observatories are almost ten years old. Scientists expect that they will send valuable scientific information about solar activity. In addition to photographs of the Sun itself, the STEREO observatories took pictures of interesting events in circumsolar space. For example, in April 2007 they took great pictures of Comet Encke as it flew past the Sun. The photographs were able to detect signs of turbulence in the tail of a comet from clumps of ionized gas.

If communication with STEREO-B is lost again, then the engineers have a backup plan. In 2019, the craft will be close enough to make direct visual contact, view it through the lens of the Hubble Space Telescope - and determine the degree of rotation. Around 2023, the Earth should catch up with STEREO-B - and then it will already be possible to contact it at close range or even bring it to Earth for study, if it is economically feasible.
Articles periodically appear in various media about the fruitless search for extraterrestrial intelligence outside the solar system, but the reality turned out to be much simpler.
In our solar system, on our star, there is intelligent alien activity daily and observed in detail. project "Stereo" literally right next to us, and we are constantly being told that these are image defects, although if you look closely at the photographs, you can see that the sun's corona sometimes covers these objects, how can an image defect be covered by the sun's corona?
At the end of October 2006, a Delta II 7925-10L rocket was launched from Cape Canaveral Florida, which launched two identical observatory satellites into space with a large set of equipment for observing and fixing the parameters of the Sun's activity. Rotating around the eccentric upholstery, for several weeks, then moving away from each other, then approaching, remaining close enough, as if lining up for a rendezvous with the moon. The first (Ahead) approached the Moon, under the influence of its gravity was thrown forward from the Earth. The second (Behind), being captured by the lunar attraction for several weeks, was thrown in the opposite direction. If you look at the NASA animation, the Earth is a green dot, the Moon is white, Ahead is red, Behind is blue, the yellow arrow indicates the direction to the Sun.
When both satellites settled in the orbit of the Sun, Ahead is closer to the Earth, Behind, behind the Earth and a little further. The satellites drifted, gradually moving away from the Earth in different directions. The mission was named project "Stereo". On the NASA animation, the Earth is a green dot, the Sun is yellow, “A” is red, “B” is blue. The orbits of Mercury, Venus and Mars are white.
The image below shows the location of the satellites for the period 2/10/2011.
All information found on the NASA website, dedicated to project "Stereo" and is freely available. After setting up the equipment in March-April 2007, high-quality images were received from satellites. In the resulting photographs from Ahead and Behind, you can see mysterious objects of clearly artificial origin. These objects were huge, appeared out of nowhere, moved at great speed around the Sun, “landed” on the Sun, took off from it and disappeared in an unknown direction. And the same thing continues to this day. Many forums on the Internet are filled with information about these objects, but information from official sources has not been received. Photos that are uploaded in real time are “contrasted”, all objects are visible in the pictures as white dots and lines. Questions asked by NASA about these objects were answered by the mission officer in charge. project "Stereo", Dr. Joseph B Human. He explained that the white dots with four blacks around them are highly magnified image compression artifacts. We will try with you to consider “defects” in images with a resolution of 2048x2048, which anyone can download and view using the links:
Image of our star from the SOHO satellite
At the moment, in addition to terrestrial instruments, many spacecraft have been launched to observe our star: SOHO, SDO, Stereo A and B. In the images below, you can view the current state of the Sun online from a satellite in various ranges.
Live image of the Sun (online)
The photo is updated daily. Sometimes it is possible to turn off the cameras on the satellite.
The sun is at a wavelength of 171 angstroms (ultraviolet), which corresponds to a temperature of about 1 million degrees.
The sun is at a wavelength of 195 angstroms (ultraviolet), which corresponds to a temperature of about 1.5 million degrees.
The sun is at a wavelength of 284 angstroms (ultraviolet), which corresponds to a temperature of about 2 million degrees.
The sun is at a wavelength of 304 angstroms (ultraviolet range), bright spots have a temperature of about 60-80 thousand degrees.
The SOHO satellite has a spectrometric coronagraph capable of taking photographs of the solar corona by blocking the light coming directly from the luminary, obscuring it with a disk and creating an artificial eclipse in the instrument itself. The position of the Sun's disk is marked with a white circle. The most prominent feature of the corona is the coronal rays, the almost radial streaks that can be seen in the images. A coronal mass ejection can also be seen with a coronograph.

One of the main instruments of the satellite is EIT, which stands for Extreme ultraviolet Imaging Telescope (ultraviolet telescope).
It shows images of our star's atmosphere taken at wavelengths of 171, 195, 284, and 304 angstroms. The bright areas in a photo taken at wavelength 304 are between 60,000 and 80,000 degrees Kelvin. 171 - corresponds to temperatures of 1 million degrees, 195 - bright areas have a temperature of 1.5 million degrees, and finally, 284 - corresponds to a temperature of 2 million degrees Kelvin.
STEREO consists of two space observatories - one in front of the Earth in its orbit, the second - behind. From these two perspectives, scientists will be able to explore the structure and evolution of solar storms as they explode from the Sun and move through space.
This movie illustrates a spherical map of the Sun as it appears now, formed from a combination of images in front of and behind the lighthouse, along with SDO/AIA images in between. The video begins by showing the Sun as seen from Earth, from the 0 degree meridian point of the line in the middle. The map then rotates 360 degrees so you can see the side of the Sun not visible from Earth.
