It’s time for the 13th seasonal sunset watch!!
- When: Wednesday, June 20 at 9:01pm (so come at 8:45pm)
- Actual sunset is supposed to be at 9:11, but at the summer solstice we noticed that the Sun set about 10 minutes earlier than the USNO [1] says it does, so I’ve moved the time of our sunset watch up so we don’t miss it. In Autumn the timing seemed to line up correctly – what will it do this time?
- Where: Solstice Park [2] – 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 summer solstice sunset at Solstice Park in West Seattle on Wednesday the 20th. 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!
