From the Help Board:
Satellites sometimes pass overhead as the telescope is observing and
reflect light in a streak across the image as they pass by. They move
quickly so their trails are always a single color: red, green, or
blue. Sometimes you can classify the central galaxy, other times there
is no central galaxy because the computer got a bit confused.Posted
