PostHeaderIcon September 22 Fall Equinox Sunset Watch–2017

It’s time for the 34th seasonal sunset watch!

We’ll also share eclipse stories and favorite moments or pictures from Cassini (RIP, now part of Saturn). If you drew a picture of the eclipse, either before or after I would absolutely love to see it.

  • When: Friday, September 22 at 6:55pm (so come at 6:35pm)
    • Actual sunset is supposed to be at 7:06pm, but we have noticed that the Sun sets about 10 minutes earlier than the USNO says, because of the horizon altitude.
    • The equinox moment is Friday, September 22 at 1:02pm 
  • Where: Solstice Park – all the way up the hill from the tennis courts (or, if you’re not in Seattle, wherever you have a view of the western horizon!)
  • Who: Everyone welcome, as usual. (Please do leash your dogs as we usually have a good number of people, kids, and other dogs around.)

Come watch the sunset at Solstice Park in West Seattle. I’ll be there even if it is cloudy because sometimes the Sun peeks through just as it begins to set, but if it is driving rain or a thunderstorm I’m staying home with some tea!

If you’re interested – here’s the timing of various celestial events  from Seattle, courtesy of the U.S. Naval Observatory Astronomical Applications Department:

    I was at Salem for the eclipse, co-hosting as an SSA at the state fairgrounds NASA booth/tent. I can relate my experience at your event if wanted. My eclipse photo album is on my FB page as an album. I am also busy as a volunteer at the Pacific Science Center in their Science Interpretation Program. I remain a member of the Everett club. I have expressed an interest to my supervisor there of hosting SSA and Project Astro events or lectures at PSC. Adding your voice in request, might help that effort. Not just for us, but for all active SSAs in the region. We could collaborate or help each other in other ways. Will try to make to to the sunset even if you don’t need my input in programming. Let me know.
