Hi Dave, It would be too hard to locate ISS in braod daylight when the Sun is more that a couple of degree above the horizon. Persistance would be needed on the part of observer, as in my opinion, roughly, there could be 75 passes for a location in a year in twilight condition and may be 6 to 12 pas...

Davej,

Thanks.

If an observation is made when the sun is less than six degree below horizon, then in my pushing observation in HA database, i decide to call it a daytime observation.

You must have got it that way also, mustn't you?

Vikas.

thanks,

It's very difficult. By the way, in your opinion which should be called a day sighting (in terms of CIVIL DAY / NAUTICAL DAY / ASTRONOMICAL DAY)? This question was bothering me since sighting and posting.

ISS Crossing Moon on 18 Sept 2009

ISS is crossing Moon for my present camping location, on 18 Sept, 2009 at 14h40m26.78s. I desire to see the event, as ground track for centre of disk crossing is just 300 mt from my camping location. My apprehension : I may not be able to watch even Moon, as it is too close to Sun ( 6 deg elongation...

However, based on simulation run on Xemphem software for my location, chances of Endeavour too, transi...
