PostHeaderIcon Winter Solstice Sunset Watch – 2013

It’s time for the 19th seasonal sunset watch!!

  • When: Saturday, December 21 at 4:05pm (so come at 3:30pm)
    • Actual sunset is supposed to be at 4:20pm, but we have noticed that the Sun sets about 10 minutes earlier than the USNO says it does, so I’ve moved the time of our sunset watch up so we don’t miss it.
    • The equinox moment is at 9:11am… but we’re watching the sunset not the sunrise because of how the park lines up.
  • 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 winter solstice sunset at Solstice Park in West Seattle on Saturday the 21st. 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 some hot tea!
