Jim, I believe the predicted time is corrected for an earth bound observer.  Though you could report observed time and actual time to emphasize speed of light time lag/delays.

Milton,

I really enjoyed your Eros light curve presentation, astronomy is one
of those rare areas where amateurs can still contribute meaningful
scientific information.

My son is hoping to do a science fair project where we use AstroIIDC
to record the reappearance of Io from behind Jupiter and by using
really precise time recording track (I believe now available on
AstroIIDC) determine the delay between the expected time and
observation time to determine an estimate for the speed of light.
