Hi again everyone,
Neither the red nor the blue second-generation DSS images show anything at
this location, even though they both show objects fainter than the limiting
magnitude of the image. If this is anything real, it must be something new.
However, the fact that it is an exact east-west trail, and is precisely due
west of the bright star that Masayuki identified, leads me to believe that
it is a reflection of some kind.
That being said, it probably wouldn't hurt for someone to do some follow-up
on it. Unfortunately, I'm not set up for that right now . . .
Sincerely,
Alan
