Golden State Star Party 2011


The 2011 Golden State Star Party is Jun 29 through July 3rd, 2011, at Frosty Acres Ranch, near the town of Adin in Northeastern California.

This is the 4th time this event has been held at Frosty Acres Ranch. Its a great location, wide open horizons 360 degrees around and some of the darkest skies possible anywhere. The mesa we observe from has room for 100s of campers.

The 2011 observing nights at Bonny Doon are posted on our calendar and events pages.

The Moon occultation Venus, Wednesday morning 4-22-2009

I woke at 4:30AM, jumped into car and raced outback of Fort Ord to watch the
Moon/Venus occultation.  Got setup about the time Venus was covered up by the moon.  At
5:30AM the fog rolled in.  No more moon!  I put everything in the car and headed east on
Reservation road fast.  Just past Route 68 pulled over in small neighborhood at 5:50AM.  Got
setup with webcam and caught rough view of Venus coming out from behind moon.  See attached file. 

International Year of Astronomy 2009

The Universe is yours to discover during the International Year of Astronomy 2009

Dec 29, 2008, Paris

With 2009 just over the horizon, stargazers around the world are busy preparing for the International Year of Astronomy. A staggering 135 nations are collaborating to bring the Universe closer to Earth. Events and activities will take place over the coming 365 days and beyond, in a spectacle of cosmic proportions.

2009 Calendar

Our club's 2009 Event calendar is all up and posted.

I've attempted to ensure all times are in current local time for Bonny Doon Airport (either PST or PDT as appropriate).   Moon phases are indicated with the approximate time of the phase.   Observing dates are tagged with the sunset time, and annotated with moon and planet rise/set times as appropriate.

I've also added the times for various public and group events.    All club members are encouraged to add their own dates to the calendar, use Create Content -> Event.
