Lunar Eclipse Viewing Party

Sunday, January 20, 2019 10:30 pm - 10:30 pm EST (GMT -05:00)

Stages of lunar eclipse

Witness the latest act in the ancient cosmic ballet at the Observatory!

  • Telescope viewing beginning with partial eclipse at 10:30 PM (observatory / rooftop; access from 3rd floor of PHY)
  • Totality ("blood moon") begins at 11:41 PM and ends at 12:43 AM
  • Partial eclipse ends around 1:45 AM

The observatory is hosting a special event for the January 2019 lunar eclipse. The main observatory telescope will be trained on the moon, along with other telescopes on the rooftop, for public viewing of the Earth's shadow crossing the full moon. Sunlight from the all the sunsets and sunrises around the world will pass though the Earth's atmosphere and into its shadow. A reddish glow will gradually sweep across the Moon over a two hour period, with the Full Moon appearing completely reddened prior to midnight!

So far the forecast shows clear skies, but any cancellations due to weather will be posted to the Observatory webpage. Also keep in mind that the Observatory is an outdoor facility, so dress warmly! 

Note: If the weather turns out to be cloudy, telescope observing will not be possible; special arrangements will apply:

  • If the weather is partly cloudy, we may elect to wait it out
  • In the event of persistent clouds or precipitation, a cancellation notice will be posted to this event listing, as well as the observatory's main webpage
