Wow! I have seen a lot of soho pictures but none as dramatic as this! I have no idea what that could be. It seems reallly strange. I will have to keep
checking back to see if anyone has any ideas.
Sometimes it may just be the simplest solution. Don't assume SOHO equipment works perfectly 100% of the time. A simple momentary misalignment with
the disc in the center of the images would likely cause a pic like this.
