Iridium Flare

Lat night I went out to look for an iridium flare. I looked on heavensabove.com and found that I would be able to see one at 10:53. It was at an altitude of 37 degrees with an azimuth of 69 degrees. I never knew what an iridium flare was until this class and I have tried see a few before but for some reason haven't been able to see any. So last night I was really excited when I actually saw one. It was a very cool sight to see. It's weird to think that iridium flares happen so often and I have never seen one or even heard of one.
