A bad photograph - sorry. You might wonder why I post pictures on the bad days. The reason is that they stand out like beacons, reminding me that I have to try harder... But given that I have posted this, I might as well explain what it’s about. In my PotD of 10th December, there’s a bright star, which I keep noticing on on clear evenings, just after sunset. I’d love to know what it is, but don’t know anything about stars. Erica was kind enough to lend me a book, but there are no quick answers with... I’m going to have to read it. Unless anyone else knows what it is?
