I'm very pleased with this observation of the light curve of the asteroid Eros that I took a few nights ago. It rotates with a period of about 5 hours, so it gets (slightly) brighter and darker over time if you observe it long enough.
Lots of things about the way computers and the Internet turned out suck, but backyard #astronomy is one place where the future is everything I could have hoped for when I was a teenager in the 90s.
