PostHeaderIcon Spring Equinox Sunset Watch – 2011

Yup! It’s that time again. Time for the quarter-annual sunset watch … only this time I’ll be 8.25 months pregnant when we meet!

  • When: Sunday, March 20, 2011 at 7:22pm (so come at 7:00pm)
  • 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.

Come watch the spring equinox sunset at Solstice Park in West Seattle on Sunday the 20th. We’ll see if the sunset lines up with the placed marker. 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 sleet I’m staying home with a cup of tea.

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

    Could you also post the time of the solstice itself (in Seattle time–just to make it easier on certain people who might need to find the time of the solstice, but who could struggle to figure out how to calculate it from GMT…. )?
