It’s time for the 27th seasonal sunset watch!
- When: Monday, December 21st at 4:05pm (so come at 3:45pm)
- Actual sunset is supposed to be at 7:05pm, 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 Monday, December 21st at 8:40pm
- 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. 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!
