The ISS pass was as predicted in Orbitron. The pass was not shown on Heavens-Above because the sun was not more than 10 degrees below the horizon, so the sky was still relatively bright.
We picked up the pass at close to 40 degree elevation, and it was quite bright (still impressive) but at a quick look at my photos I can't pick a trail
. I took a couple of photos prior to visually finding it using the realtime azimuth and elevation figures from Orbitron to guide the camera as well. I'll have to have a play in PS CS2 to see if I can extract any data or not. It doesn't look promising at this stage though... the sky was too bright to provide any contrast to the trail...
We also just happened to be looking at the horizon low in the SW when the ISS returned later at about 21:00. I quickly fired up Orbitron to confirm it was the ISS again.
Fahim, what you describe sounds like an Iridium Flare most likely. Since I don't know where you were I can't say if it was the ISS or not. The ISS does occasionally flare though.
