Hey All,
Watching the NASA channel this evening (Monday
July 10, 1:40 UTC)I saw where the ISS/Shuttle was
approaching the Dallas TX USA area from the northwest
right at sunset. I quickly pulled up my HA site but it
didn't show a "visible" pass. I went outside and
looked straight up into the clear sunset/bright
twilight sky and there they were going overhead, very
visible. So what is the criteria that HA uses for a
"visible" pass, e.g.; does the sun must be more than 6
degrees below the horizon or something like that? I
believe you should be able to see these spacecraft in
daylight. Anyone ever seen that occur?
BTW, for all of you that watched NASA TV on your cable
or dish TV systems, is NASA audio out? It is on my
cable system and COMCAST is blaming NASA. Just
wondering if this is a local problem.
Regards,
Jeff Umbarger
