PostHeaderIcon Winter Solstice Sunset Watch 2011

In light of the Lunar Eclipse this past weekend, it’s time for the 11th seasonal sunset watch!!

  • When: December 21, 2011 at 4:05pm (so come at 3:30pm)
    • Actual sunset is supposed to be at 4:20, but at the summer solstice we noticed that the Sun set 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. I added another 5 minutes for the tall trees of Lincoln Park blocking our view. In Autumn the timing seemed to line up correctly – what will it do this time?
  • 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 Wednesday the 21st. We’ll see if the sunset lines up with the placed marker (it did for summer, but will it for winter?). 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!

    I spent almost three months in your area this Summer and Fall, but was unaware of your wonderful gatherings. Alas, tonight finds me back “home” in Southern California, but trust me, I will be there in Spirit.
