I went outside at 20:53 last night to see the Iridium flare. I thought an annoying cirrus cloud from the off-coast pinwheel low would get in the way, and the sky was still rather bright. But I saw it, nearly overhead, rather than at 69 degrees. It shone intensely bright (if Betelgeuse went supernova, it would be a hundred times brighter!) and then faded. It was out in about 30 seconds.
