Del Valle Observing Site

About the Del Valle observing site

The East Bay Regional Park District (EBRPD) has granted TVS a Special Usage Agreement which allows regular and patron club members in good standing and their guests to observe at a specified hilltop location within the park any night of the year beyond the 10:00 PM curfew and until daybreak. While this site is not as dark as our Hidden Hill Observatory observing site, it is much closer to Livermore, and therefore more convenient. To access the Del Valle site, you need to fill out and sign the user agreement below and submit it to the club. The agreement can also be found in a PDF file. You must also notify the East Bay Parks every time you intend to use Del Valle.

Here is the Clear Sky Chart for the Del Valle observing site:
