The Geminid meteor shower peaks tonight (Dec 13) into early Dec 14! 🌠
The waning crescent Moon won’t rise until after 2am, so viewing should be good. Under perfect skies you might see ~100 meteors/hr. Bundle up & hope for clear skies!

Tonight, there's a lot to see in the eastern sky (weather permitting!) The waning gibbous moon will shine near Jupiter and the bright constellation Orion the Hunter. Jupiter will be near the twin stars of Gemini, Castor and Pollux. And the brightest star in the sky, Sirius, will be nearby. They’ll be spectacular and visible through dawn! SOURCE: Earthsky.org

If you're up before the sun, take a peek at Mercury as it rises in the E-SE, about 90 min. before the Sun. It’s bright & will get even brighter early in the month! It's not always easy seeing our smallest planet, but these conditions are favorable, weather permitting!

Just a quick THANK YOU to those who contributed to our Giving Tuesday campaign yesterday. All donations made during the month of December will be matched by our FRIENDS of the Horwitz-DeRemer Planetarium...so your impact will be doubled! #wherethestarshangout #givingtuesday
