Hi Chris,

You can use PREDICT for this very purpose!   You can look days and months ahead to see when a satellite in in eclipse, how much illumination it should receive, etc.  It's really slick.

Pick your OS, download, read a bit, and have at it.

Thanks to Bruce WB9ANQ for directing me to this software just a few days ago and to John KD2BD for a great program!

Hi All,

I have never been able to get a straight answer on this one, but does InstantTrack or any other program show you the long term non-eclispse/eclispe period, or is there a way to calculate this?

How do we know that PCSAT and UO11 are going to HIT sunlight or not for a period of time?

I can see from Orbitron the realtime, but not anything in the future?

Thanks,

Chris
