December Night Sky

One of the fun things about winter is the night sky.  Cold, clear, winter skies are characterized by a lack of humidity and if you live in the country there is very little urban light pollution creating some spectacular opportunities for star-gazing.    

December brings a couple of meteor showers to the night skies.  The more prolific of the two is the Geminids with as many as 120 to 160 shooting stars per hour. 

Shooting starts are most often associated with the Earth’s passage thru the debris field of a comet.  The Geminids are a bit of a mystery as they are related with an extinct comet which also happens to be a near-earth asteroid named 3200 Phaethon.

While competition from the light cast by the Cold Moon could be a challenge this is a show you do not want to miss.  The best viewing should start the evening of Friday the 13^th and peak on Saturday evening the 14^th. 

December 17^th to the 26^th brings the Ursid meteor shower with 5  to 10 shooting stars per hour as the Earth passes thru the debris field of Comet 8P/Tuttle.

Peak action coincides with the solstice the evening of the 21^st and 22^nd.  Again, there will be competition from persistent moonlight.  Your best opportunity will be before moonrise on Saturday, December  21^st .

Mark your calendar and if your catch a cold, clear, winter sky bundle-up and take some time to sit outside and observe the heavens. 

There’s no mosquitoes this time of year!
