Iridium flares are a really neat night sky phenomenon to look for. The predictions can be found on satellite tracking sites [1]. I caught one by accident when I noticed a satellite passing overhead on my way to my car one night. Over the next few seconds it increased to dazzling brightness, and then it disappeared just as quickly. I couldn't believe my luck.
