- When: Monday, June 21, 2010 at 9:11pm (so come at 8:30pm)
- Where: Solstice Park  (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 Monday. 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 I’m staying home with a cup of tea.
If it is clear we’ll bring a telescope or two to take a look at the Moon after the Sun goes down – and Mars and Saturn if we stay until it is dark enough. We will not be able to see the comet  – that rises a little before 3am, and I plan to get some sleep before Tuesday. You’re welcome to look for the comet on your own though!
