(meteorobs) Probable cosmic ray and not a meteor

It would be more accurate to say there was a single cosmic ray, and at
least three areas of the sensor that were synchronously exposed to
secondary particles when that cosmic ray struck something outside the
sensor itself.
Whenever you see synchronous flashes on a CCD there is good reason to
suspect a cosmic ray (or high energy particle from the Earth) was involved.
The trace near the Moon is too long to appear on a single frame if it
were meteoric in origin, and that doesn't explain the synchronous
flashes elsewhere in the frame.
