Upcoming Events



Jazz Under the Stars

Jazz Under the Stars is a FREE monthly public stargazing event! Occurring on the Saturday after the 1st quarter moon (check our Events Page), join us on the 4th floor planetarium for a night of smooth jazz, bright stars, and a lot of fun! We play our jazz from CSM's own KCSM 91.1. Founded in 1964, KCSM has grown to become one of the top 35 most listened to non-commercial stations in the US. With their help, the Astronomy department at CSM opens its observatory doors and balcony, for a night of science and fun! We operate for public viewing four 8” dobsonian telescopes, prefect for viewing the planets Venus, Mars, Jupiter and Saturn. We also have a 140mm refractor, with which we view the craters on the moon. Finally, our 8’ schmidt-cassegrain is for our deep sky needs. It can peer deep into globular clusters, and nebulae! Our astronomers will also be available for questions and conversation, which you wouldn’t get anywhere else! Feel free to ask us your questions about the cosmos. Occasionally we even have the chance to image galaxies! Don't miss out, join us at our next Jazz Under the Stars!!

Dress warmly. Free parking in Marie Curie Lot 5. Directions are available on the Maps, Directions & Parking page.
This event is weather dependent. Latest weather updates.
No food or drinks in the Observatory. Children are welcome and must be attended at all times.

Cameras for Allsky Meteor Surveillance (CAMS) - A SETI Project 

CAMS, a SETI project, is an automated video surveillance of the night sky to validate the International Astronomical Union's working list of meteor showers. It's mission is to discover previously unknown meteor showers and to triangulate and locate meteorites. CAMS was founded in 2010, but established at CSM in 2012 in connection with Peter Jenniskens, Senior Research Scientist at the SETI Institute. CAMS has over 80 camera's in the Greater San Francisco Bay Area, and over 260 cameras worldwide. This mission has led to the discovery of over 60 new meteor showers including Delta MensidsFebruary epsilon Virginids, and R Lyrids


Oct 17 fireball CAMS
Fireball captured on CAMS camera -CSM Observatory


Our observatory's CAMS video camera captured a bright fireball over the Bay Area on the local evening of 10-17-12. This looping video shows the Oct. 17 fireball, with a field of view ~28 degrees.  Six meteorites were discovered from triangulating data from CSM and Santa Rosa. All six meteorites were found in the town of Novato, located about 45mins north of San Francisco. These meteorites were discovered to have a previously unknown class of metal-organic compounds known as dihydroxymagnesium carboxylates. Link to SETI article. Special thanks to Dave Samuels in processing/managing CAMS data. See the latest CAMS update.

We image nightly with a single, Watec 902 H2 Ultimate video camera, producing a 26.8 x 22.1 degree FOV centered on Azim (deg) 263.205, Elev (deg) 47.283. Processed data is available for student analysis, and sent to Dr. Jenniskens. Check out this sample video of the Quadrantids meteor shower taken January 4, 2012.

The Observatory

Our observatory is of the roll-off roof design. Therefore, it does not look like the typical domed observatory. An advantage of this design, is that more telescopes can be used simultaneously. In addition, the observatory can quickly reach thermal equilibrium. This results in steadier views through our telescopes.

 

RC 20 Telescope

20" RC Telescope

General Information:

  • Reflector Telescope
  • Apature: f/8
  • Field of View: 15.6x23.4 arcmins
  • SBIG STL-6303 CCD
  • Chip Size: 18.4x27.6 mm
  • Pixel Size: 9u x 9u

Our 20" Ritchey-Chretien telescope from RC Optical Systems delivers quality images of the night sky. The RC sits atop a Paramount ME mount for location and tracking of distant objects. Attached is an SBIG STL-6303 CCD camera for imaging deep sky objects and measuring stellar magnitudes.  A 500mm Borg refractor rides "piggyback" on the 20."
