PostHeaderIcon March 19 Spring Equinox Sunset Watch — 2016

It’s time for the 28th seasonal sunset watch!

  • When: Saturday, March 19th at 7:10pm (so come at 6:45pm)
    • Actual sunset is supposed to be at 7:22pm, 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 Saturday, March 19th at 9:30pm
  • 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.
  • Bring (optional): Your smartphone or tablet with a stargazing app. If you do, I’ll spend a few minutes showing you how to use the app. Well, I’ll try anyway, this part of the evening is in beta testing. ;)

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 sleet I’m staying home with some hot tea!
