There are several astronomy club events and a star party on the calendar for the coming week.
The Tacoma Astronomical Society will hold its monthly meeting at 7:30 p.m. Tuesday, December 6 in room 175 in Thompson Hall on the University of Puget Sound campus. Program information had not been published as of this writing.
The Battle Point Astronomical Association has a big evening of events planned for Saturday, December 10. The monthly “parent-kid date night” from BP Astro Kids will be all about stellar DNA, as participants learn about the spectral makeup of common elements and how we know what the sun is made of. They’ll also create and decorate their very own take home spectrometers to investigate everything from hydrogen emission lines to the spectrum of light bulbs at home. Two shifts of events start at 5 p.m. and 6 p.m. at the association’s Edwin Ritchie Observatory on Bainbridge Island. Following at 7:30 p.m. BPAA puts on a planetarium show “Navigating by the Stars.” Before GPS was invented people found their way around by the positions of the Sun, Moon, planets, and stars. Blue water cruiser Frank Petrie will talk about the basics of navigating with a sextant, and why it’s harder than Hollywood would have you believe. The show starts at 7:30 p.m. Astronomical observing will follow if the weather is good.
The monthly Covington Community Park star party will be held at—where else?—Covington Community Park at 6 p.m. Friday, December 9. The popular suburban star party is a joint venture between the Seattle, Tacoma, and Boeing Employees’ astronomical societies.
Up in the sky
Uranus and Neptune can be a little difficult to find, but it will be a little easier this week because both will appear close to the Moon, Neptune on Tuesday and Uranus on Friday. The Sky This Week from Astronomy magazine and This Week’s Sky at a Glance from Sky & Telescope offer more observing highlights for the week.
