Re: Simbad

Shawn and all,

Hmmm!  I guess I will eventually learn this stuff.  I could have easily 
searched my data where stars would be rising.

OK, you are right on the typo.  It should be 96.9791, 8.4018

What say I search my data around 14 h?  Would this be in a good position 
for you?  The place where I don't have much data is 18 to 24 hours.   I 
suspect it will take about a week for me to get the new computer loaded up 
and start processing a new region.  The new computer has not yet arrived, 
but this looks like a good project for it.

It looks like I will find lots of prospects.  I can feed anyone that wants 
to take their telescope and make a more complete curve.

I have 146 measurements spread out over 5 days for the suspected variable 
if it is the one at 109.6394, +9.4944, I hope this will be enough to 
determine a period.   It looks like an eclipse, but I have two trailing 
edges and no leading edge.  So it will be hard to tell unless computer 
software does something wonderful.

Thank you for looking.
