Re: [amsat-bb] SatPC32 "sun tracking"
Bob,
There is an auxiliary program in the SatPC32 folder called SuM.exe which track both the sun and moon.

Thanks ALL! Found it (SuM.exe). But it won't let me easily slide around in time.
So I just went back to my 20 year old copy of Instantrack, verified that it gives same result as SuM and now I'm good.
I used IT to see how many hours of sun a south facing solar array would be illuminated at what elevation angle.
For my latitude (39 degrees), I developed this table in about a minutes work: 7 Hrs over +/-49 deg AZ above 10 deg EL 6 hrs over +/- 43 deg AZ above 14 deg EL 5 Hrs over +/- 37 deg AZ above 18 deg EL 4 Hrs over +/- 31 deg AZ above 21 deg EL 3 Hrs over +/- 24 deg AZ above 24 deg EL
To figure out where to top off some trees.

Bob, for your purpose you could use SumListen.exe (also in the SatPC32 program folder). It outputs lists with azimuth and elevation of Sun and Moon to the screen and/or printer for selectable increments and periods.
