Hi folks: I think there are many ways for locating iridium flares. For me I will do a quick check on the Heavens-above to pick the best candidate(s). If I want to do photography etc I will need to locate the exact flare location vs the background stars. I use Rob's excellent skymap program (download the latest tles first) which indicate the exact flare location vs the rest of the trajectory in yellow. For general x1 view the alt/az will suffice in for my through the window obs ( with know alt/az of surrounding landmark). Since the compass is affected by ferrous objects, I find I can have as much as 10-15 degree errors in az..using a cheap dash-board compass. DO you have similar problem? rgds ykChia http://www.geocities.com/ykchia_1999/index.html ----------------------------------------------------------------- Unsubscribe from SeeSat-L by sending a message with 'unsubscribe' in the SUBJECT to SeeSat-L-request@lists.satellite.eu.org http://www2.satellite.eu.org/seesat/seesatindex.html
