The below video is a little over 4 minutes long. In the video the author UFOvni2012 makes several claims. For the purpose of this thread I will investigate 2 of the 3 claims made in the video, since the coronal holes was previously discussed here; https://www.metabunk.org/threads/debunked-giant-black-sphere-hovering-near-the-sun.469/
The first claim made in the video deals with streaks of light seen around the sun usually during or after a CME or solar flare event. Below are screen shots of some of the images;
NASA's SOHO page explains why these occurrences happen.
I would appreciate some help in explaining why the planet in view is moving across the screen from right to left. The only thing I can think of that would cause this is if that the satellite orbits its lagrange point, http://map.gsfc.nasa.gov/mission/observatory_l2.html, and it's the orbit of the satellite swooping past the earth or moon that cause this planet to appear like it's moving in the wrong direction. So this isn't an Alien Mothership as discussed in the video. The video came out a few days ago on the 25th of September so I thought it deserved to be debunked...

In the next part of the video he shows a video that was taken from SOHO which shows a planet size disc moving across the plane of the sun, and argues that the object due to SOHO's location should move from left to right, but this object moves from right to left. Here is an image of where SOHO sits as it orbits the sun;WHAT ARE THOSE FLYING SAUCER-SHAPED OBJECTS IN THE LASCO IMAGES?
The "funny-looking spheroid" is a typical response of the SOHO LASCO coronagraph CCD detector to an object (planet or bright star) of small angular extent but so bright that it saturates the CCD camera so that "bleeding" occurs along pixel rows. There is a bright horizontal streak on either side of the image, because the charge leaks easier along the direction in which the CCD image is read out by the associated electronics.
CCD stands for charge-coupled detector, and refers to a silicon chip, usually a centimeter or two across, divided into a grid of cells, each of which acts like a small photomultiplier in that an incoming photon knocks loose one or more electrons. The electrons are "read out" by row (fast direction) and column (slow direction), the current converted to a digital signal, and each cell or picture element ("pixel") thus assigned a digital value proportional to the the number of incoming photons in that pixel (the brightness of the part of the image falling on that pixel). This is the same kind of detector as is used in a hand-held video camera, though until recently, the analog-to-digital conversion was left out in consumer devices.
If you point a video camera at a very bright source (say, the Sun), the image "blooms" or brightens all over --- there are so many electrons produced in the pixels corresponding to the bright source that they spill over into adjacent rows and column, perhaps over the entire detector. Better CCD's will "bleed" only along the fast readout direction (a single row), and perhaps a few adjacent rows.
The LASCO and EIT CCD cameras include "anti-bleed" electronics which limit the pixel bleeding around bright sources to less than the full row (and usually no adjacent rows). In the case of a marginally too-bright object, the pixel bleeding will be only a few pixels in either direction along the fast readout direction. Thus, the "flying saucer" images.
A few of the LASCO images that have appeared on the "extraterrestrial" Web sites show much larger and brighter, but still saucer-like features. These images are in fact obtained with the instrument door closed, but with an incorrectly long exposure. The big "saucers" result from massive pixel bleeding along every row of the detector containing part of the image of the "opal," or small diffusing lens, in the instrument door, that is used for obtaining calibration data.
If your correspondents still prefer to believe that the pixel-bled images of planets or bright stars are something else, ask them why the extended part of the "saucers" (i.e., the pixel bleeding) always occurs in the same direction relative to the image --- even when the spacecraft is rolled relative to its normal orientation relative to the Sun. http://soho.nascom.nasa.gov/explore/faq.html#FLYING_SAUCER
