PostHeaderIcon June 20 Summer Solstice Sunset Watch – 2015

It’s time for the 25th seasonal sunset watch! Wow. That’s a lot. We should probably have some kind quadrans-quarter-ennial, or icosipenta-seasonal-versary, or quasqui-quadmensiversary celebration, don’t you think?

  • When: Saturday, June 20, 2015 at 9:00pm (so come at 8:45pm)
    • Actual sunset is supposed to be at 9:11pm, 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 at Sunday, June 21, 2015 at 9:38 AM … but we’re watching the sunset the night before 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 sunset at Solstice Park in West Seattle. The stone markers have been removed for upkeep, so if they aren’t back yet, we’ll mark the location of the sunset ourselves. The earthworks are still in place, so we can definitely still see the alignment. 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!

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