PostHeaderIcon June 16 Summer Solstice Sunset Watch — 2018

It’s time for the 37th seasonal sunset watch!

  • When: Saturday, June 16 at 8:50pm (so come at 8:30pm)
    • Actual sunset is supposed to be at 9:09pm, but we have noticed that the Sun sets about 10 minutes earlier than the USNO says, because of the horizon altitude.
    • The solstice moment is Thursday, June 21 at 3:07am 
  • 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!
