This year the Geminid Meteor Shower, traditiononally arguably (Perseid Meteor Shower) the best meteor shower of the year, is expected to peak on the night of December 13 into the morning hours of December 14, accompanied by the December Full Moon. In Pittsburgh the Moon is Full, December 13 at 7:05 PM EST with Moonrise at 5:06 PM EST that evening. This year’s mating of the Full Moon with the peak of the meteor shower is disadvantageous for optimal meteor viewing with the bright moonlight expected to wash out all but the brightest meteors.

Early Evening Meteor Viewing Windows on Wednesday and Thursday Evenings, Before 6 PM and 7 PM , Respectively, Punctuated by Spectacular Moonrises

However in the nights immediately following Geminid peak the Moon rises approximately an hour later each night allowing an early evening window with a moonless sky as shown in the Stellarium. org screen capture diagrams below. The bonus at the end of the Moonless window is the opportunity to see the spectacle of Moonrise in the crisp December air. Native Americans named the December Moon the Cold Moon or the Long Night’s Moon. When the Moon is near the horizon an optical illusion makes it appear even larger. This year, this month’s moon is at perigee or a part of its elliptical orbit when it is closer to the Earth giving it an added boost in size. In recent years these perigee moons have been popularly named Super Moons. The Amateur Astronomers Association of Pittsburgh is not planning a public Geminid Meteor Viewing at the time. Geminid viewing opportunities will improve in 2017 when there will be less competition from Moonlight.

We encourage you to observe the 2016 Geminid Meteors and the December Full Moon on your own.  Remember to dress for the weather and to be alert and visible when out in the dark. For a warmer option view the Geminids live on Slooh beginning at 8 PM, Tuesday evening: From YouTube  here.
