What could this be on SOHO

Select lasco c2 and select movie.

Looks interesting.. I've no idea what it is though. It doesn't look like an image artifact anyway!

Taken from another forum after Googling it a bit.

The below is a reply from NASA to someone who sent them a letter asking what was the above image.

Subject: Letter from nasa.

This was sent to me from nasa when i asked about the 10.10.10 soho image showing that craft lookin object. Thought you would be interested...

Hi DukeTTT

I looked into the image you were questioning on October 10 2010 12:12 UT. This artifact is actually quite normal in the Lasco images but due to it's shape and structure it is quite puzzling. The easy answer is "cosmic ray" particles. Cosmic rays are energetic particles which travel at fast speeds and at times pass in front of the the Lasco cameras while an image is being exposed with the camera shutter open. They can be a number of different types of particles and any type of sizes. Most cosmic rays in the lasco images look like narrow streaks. This particle seeming to be in comparison with the size of the Sun which is depicted as the white circle in the center of the Lasco images looks as if it is 1/5th the size of the Sun itself. This is not true, the particle is itself very close to the optics lens of Lasco C2.

Trying to accurately explain the shape and why it it looks the way it does is the tough part. The image 2 below is a raw image which came from SOHO. There has been no subtraction or alteration of this image such as scaling or brightening. The image is showing exact photons (or protons) the Sun is omitting and the particles surrounding the view between SOHO and the Sun. I can look at the pixel brightness (pixel intensities) as counts, the areas over the particle are above the 16,000 range and have saturated the pixels. When pixels get saturated they will also bleed over into adjoining pixels. This is how I can explain the weird shape which looks like a bird, or leaf, or a Batman logo. The pixel brightness usually spreads in the left and right directions. The image 3 below is blown up enough to show where pixel saturation has spread. It does look like this cosmic ray was a much more narrow streak at one point until bleeding in the closer point to Lasco has happened.

I sure wish I could be more visually explanatory about the artifact in the image. Multiple images in sequence that show the same artifacts like planets, stars, and comets are much easier to explain. Single images that have evidence of particles and such are very difficult.

I hope this helped! Thank you for using SOHO data.

Started skimming through the entire thread and some of the images these guys have found on LASCO C2 are pretty cool

Here's what the OP is talking about.. it doesn't look anything like the artifact which was posted already.

SUNDIVING COMET: A newly-discovered comet is diving toward the sun, and it will probably not survive the encounter. Click on the image to view a movie of the death plunge:

There was a nice CME before the above appeared in shot

If you switch to LASCO C3 you can watch the comet come in from a distance You can see it on the 13th at around 10:00.
