Mauna Kea Geminids
This is a movie of last night's sky from Mauna Kea and is well worth downloading. If you're wondering "Why is the sky blue but I can see the stars?" that's because for the first half of the night, the moon was up! At around midnight, it sets, creating a second dramatic mountain-shadow. After moonset, the sky becomes dramatically darker as the meteor activity picks up.
The lights in the distance are Hilo.
