UPDATE -The Roll-Top Observatory is open to the public on clear Friday nigjhts

If the weather cooperates, on Friday Night February 10th the Analemma Society will hold a special Public Viewing at Turner Farm.  Volunteers will be available at Roll-Top Observatory to help you watch the PENUMBRAL (PARTIAL) LUNAR ECLIPSE

We continue to invite the public to bring their own telescopes and set up outside the Roll-Top. There is more to see than just the moon

Please double check the weather and sky before attending.  Check our Observing page for the Clear Sky Chart and Analemma Tweets for last minute messages.

The Roll-Top will open just after sunset at 6:15pm and remain open until 9:30pm.  Here is a timetable of the lunar eclipse on February 10th, 2017:

5:32 PM     Penumbral eclipse begins (all times Eastern Standard Time)
5:34 PM     Moonrise
5:41 PM     Sunset 
6:09 PM     End civil twilight
6:15 PM     TURNER FARM PARK OPENS
7:33 PM     Full Moon
7:44 PM     Maximum Penumbral eclipse
9:30 PM     TURNER FARM PARK CLOSES
9:53 PM     Penumbral eclipse ends

Bundle up with warm clothing - Winter weather is here. The Roll-Top observatory has an enclosed classroom, but the observatory room is not heated and open to the sky.  In the classroom we will have lunar charts and other astronomical books.

There are 4 telescopes set up for viewing in the Roll-Top observatory including a 7" high quality refractor.  For public sessions, we may also have telescopes set up outside the building along the walkway to look through. Members of the public are welcome to bring their own telescopes and set them up as well. If you bring your own telescope equipment and have not been at one of our public sessions before, we recommend you contact one of the volunteers upon arrival so we can guide you on where to set up.

When you pull into the access road leading into the park, follow the road to the parking lot that will be to the left. Please put your headlights on low when entering the parking lot.  All visitors must park in the parking lot. Enter through the pedestrian gate in the Northwest corner of the parking lot and follow the walkway up to the Roll-Top building (the squat building with the moveable roof). For public sessions, the Analemma Society will have a coordinator present to greet people and provide directions. But if the coordinator is busy or providing assistance inside the building, enter through the gray door on the walkway side of the Roll-Top building.

Beside the lunar eclipse, the planets Venus, Mars, and Uranus are visible for observing in the evening during February.  The Orion nebula (M42), the Pleiades (M45), the Andromeda Galaxy (M31) are all up for viewing along with double stars, star clusters, planetary nebulas, and galaxies. The constellations of Andromeda, Cassiopeia, Orion, Taurus, Gemini are now prominent in the evening winter sky.

These public observing sessions are open to all. We get everyone from families with older kids, families with young children, individuals, couples, and students attending these public sessions.

These events are very weather dependent. Please check the Analemma tweet page on this website (or directly at @AnalemmaSociety ) for updates on Friday if the weather looks questionable for that night.
