First, the bad: The Geminids shooting stars will be competing with a bright moon, making some of the meteors difficult to see.
The good news: Geminid meteors are among the brightest of any of the annual showers, so you may be able to catch a great show in the skies above Reston.
NASA reports that the Geminids are a relatively young meteor shower, with the first sightings occurring in the 1830s with rates of about 20 per hour.
Over the decades the rates have increased, regularly spawning between 80 and 120 per hour at its peak on a clear evening.Earthsky.org calls the Geminid meteor shower "one of the finest meteor showers visible in either the Northern or Southern Hemispheres."
The description continues:
"The meteors are plentiful, rivaling the August Perseids, with perhaps 50 to 100 meteors per hour visible at the peak. Plus Geminid meteors are often bright, so, if there’s a bright moon, many meteors may be able to overcome the harsh moonlight.
"These meteors are often as good in the evening as in the hours between midnight and dawn. In 2013, a bright waxing gibbous moon will interfere with the Geminids throughout most of the peak night. Your best bet is to watch on the mornings of December 13 and 14, from moonset until dawn."
