The full Moon this December 15 reigns as the northernmost full Moon until December 27, 2023. This moon is called the long night moon. The moonlit nights this middle December make up for the waning days of sunlight in our northern hemisphere. On December 15 watch as the Moon rises around sunset and sets around sunrise, lighting up the sky for the whole night.
The Geminids-active from 12/7-12/17 hit their peak on the 13th. These have been consistently great for the last few years, even better than the Leonid. Maybe not as bright, but much more frequent.
