The second-best meteor shower of the year (after the Perseids) occurs next Wednesday night, December 13th. This shower can produce as many as 120 meteors per hour, but this would be at its strongest showing, in a very dark sky without trees or hills. More likely, we will see 20-30 meteors an hour, which is still an impressive rate. Unlike most other showers, the Geminids are not the remains of a comet consisting of fine grains of sand. The Geminids are associated with the asteroid 3200 Phaethon, which has an orbit very similar to a cometary orbit, and also passes relatively near the Earth. This results in the meteors in the Geminid stream being larger on average than those in a typical meteor shower, which also means the Geminids typically have a large number of "fireballs" - very bright meteors with long trails. Even seeing just one of these will make the night memorable.
Although the Geminids, like most meteor showers, peaks at about 2-3am, meteors will be seen as early as 9pm. I typically go out at 9 and stay out for a couple hours to judge clouds and the rate of the shower. If it is impressive, I'll dare to stay out later. Face east if you start in the evening. By 1am, the point at which the meteors seem to come from will be directly overhead.
Hope for clear skies, and temperatures above freezing, and be sure to bundle up if you do go out for the Geminids.
