Over on the BAUT forum, someone pointed out this image
http://www.bautforum.com/attachments/quest...813_0918_c3.jpg I looked through the SoHO images to be sure it wasn't a hoax, and this image did appear on the official sight with no obvious artifact like this in either the image before or after it. So it is obviously not a giant comet with a coma twice the diameter of the Sun which only appears for a few minutes... it is probably an artifact inside or right next to SoHO. Does anyone have a good guess as to what it is? |

Looks to me like a floating piece of lint in the optics, that is out of focus.

QUOTE (hendric @ Aug 20 2008, 03:02 PM)  Looks to me like a floating piece of lint in the optics, that is out of focus. I just mentioned this same idea over on BAUT. This 'event' occured during the Perseids. I wonder if some tiny dust particle collided with the camera lens during the exposure, and the haze we see is from a tiny amount of vaporized glass' smoke trail while the shutter was open. BTW, I've done no math or other physics to guess what such a pattern would look like. |

I'm having a bit of difficulty visualizing what 'during the Perseids' could even mean, since isn't SOHO about a million miles away?

The Perseids cut a fairly wide swath through the solar system. The Earth, moving at 19 miles a second, is in them for a few days (millions of miles). |
