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?

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!
