Stargazing at SMA

Due to the weather, Stargazing night has been rescheduled for Wednesday, Aug 31 at 8PM

The observatory at SMA seems to be a little known secret. Those who do discover it are impressed by the facility. At present we are not offering an astronomy class, but may do so again when schedules permit. The observatory is open a few times each semester for students and general public. These sessions are led by Ron Carman, amateur astronomer and former Academy student who attended in the 1950's.

We will have the first star party of the fall semester on Monday evening, August 29 beginning at sunset (approx 8:00 PM) until around 9:30 PM. Weather permitting we will have four planets visible after sunset: Venus, Mars, Jupiter and Saturn. It's rare we get to see all four in the sky at the same time. We can also see several nice star clusters and double stars of varied color. The Great Hercules Cluster and Wild Duck Cluster will be high enough to observe easily. After it gets dark we can easily see the Milky Way as well as several bright constellations.

Come up to the observatory and see the wonders of this universe. You may park in the upper parking lot near the RCC and walk back to the observatory. Closed toed shoes are advised. Please, turn off your automobile headlights and no white light such as flashlights and cell phones.
