A Scottish photographer has managed to get some pictures of the Geminid meteor shower on its FINAL night above the UK. Amateur astronomer Graeme Whipps picked up 13 meteors on camera in the dramatic display above Pitcaple in Aberdeenshire last night (Sun). "There was a little bit of airglow, an active burst of aurora, distant lightning flashes and last, but not least, the Geminids," said Graeme, 50, who works as a meteorologist. "It wasn't as bright as the 12th and 13th but they were much more frequent, although mostly short and fast moving." The shower is an annual occurrence which happens when the Earth crosses paths with a trail of rocky debris left behind by an asteroid known as 3200 Phaethon. The debris burns up when it enters the Earth's atmosphere, giving the appearance of a "shooting star."
