Meteor showers
- Geminids — peaks 14 December, radiant in Gemini (up to 150/hr). The richest shower of the year; the radiant reaches a useful altitude after local midnight, so it rewards southern observers well. A thin 10% Moon leaves the sky dark.
- Ursids — peaks 22 December, radiant in Ursa Minor (up to 10/hr). A circumpolar northern shower whose radiant never rises from Victoria. A bright 86% Moon interferes badly this year.
