Open Houses
The Drexel Physics Department hosts a Telescope Open House on the first Wednesday of each month at 30 minutes past sunset (for 2 hours). Pending the state of the pandemic (to be evaluated each month), we will host open houses as follows in 2021.

Wednesday, December 1st, 5-7pm

Weather Status: GO, but will likely cloud up before 7pm.

Please consider the observatory (and the surrounding roof deck) as indoor spaces. That is, masks will be required at all times.

With the exception of the September date, we hope that these events can be open to the public (subjects to Drexel's pandemic operation rul\ es, which includes required vaccinations and mask wearing).

Next public observing session:

Wednesday 6 October: 7-9pm

Weather Status: TBD

3 Nov. 2005 turnout

Directions to the Observatory: Enter the Main Building. Go up the main staircase to the 3rd floor. Walk around to the south-east corner of the floor (directly above the coffee shop on the 1st floor). Walk through the Picture Gallery hallway. Take the stairs at the end of the hall (up a small landing) to the 4th floor. Follow that hallway all the way to the end. Take the stairs to the roof of the building.


Night observing

Monthly Schedule

We typically open on the first Wednesday of each month, at the time specified below.

On the first Wednesday of every month, roughly 30 minutes after sunset, the Drexel University Physics Dept. invites the public to attend an observing session atop the Main Building at Drexel University. The program is directed by Professor Gordon Richards with the support of graduate and undergraduate assistants. We view a variety of celestial objects, from planets, nebulae, star clusters, to comets. These objects are seen atop the Main Building via a Meade LX200GPS Telescope with Schmidt-Cassegrain 16" Optics. This makes the Joseph R. Lynch Observatory the largest in the city of Philadelphia.

Solar observing

We recently acquired a new Hα telescope with an easily portable mount. Watch the quad between Disque and Korman halls or the area between Disque and the Main Building on clear days. We will usually have the solar telescope set up in the quad in the afternoon, on open house days.

For an approximation of what you will see through our telescope, see the Solar and Heliospheric Observatory's Latest EIT 304 Image website. The more activity you see in that image (ultraviolet light at 30.4 nm), the more activity you will see in our telescope. Keep in mind: the sun changes on an hourly basis, so tomorrow's sun might look quite different from today's!


The Joseph R. Lynch Observatory has been made possible by the Generosity of Joseph R. Lynch '58 and the GE Foundation.
