With the last new Moon of the summer coming up Sunday there are three star parties on the docket in the Northwest.
The annual Brothers Star Party, formerly the Mt. Bachelor Star Party, will be held Sept. 9-13 near Brothers, Oregon. It’s some 42 miles east of Bend at a site that wins accolades for darkness.
Information on the party’s website is somewhat sketchy, and I wasn’t able to find specific directions to the location for the event, but there’s a registration form that indicates either advance or on-site sign-ups are available. There’s also a Facebook page for the star party, which is a fundraiser for the Oregon Observatory at Sunriver.
The Seattle Astronomical Society will hold two star parties this weekend. One will run from Sept. 11-13 at Brooks Memorial State Park near Goldendale. The other will be Saturday, Sept. 12 at the Rattlesnake Mountain Trailhead. Both of these are for SAS members only, but it’s easy to become a member and learn about the details for these two good observing opportunities.
Astro club events
Tacoma Astronomical Society holds one of its public nights beginning at 9 p.m. Saturday, Sept. 12 at the Fort Steilacoom campus of Pierce College. They’ll have an indoor presentation about the Hubble Space Telescope, and outdoor observing if the weather permits.
The Battle Point Astronomical Association starts its events at 6 p.m. Saturday with a kids’ show in the John Rudolph Planetarium at the Edwin Ritchie Observatory on Bainbridge Island. That will be followed at 7:30 p.m. by their main presentation about the Dawn mission to Ceres. If the weather is good for observing they’ll give you a look through the observatory’s 27.5-inch scope. BPAA shows are free for members, $2 suggested donation for non-members.
