Anchorage: sunrise 4:25am, sunset 11:40pm. that makes about 19 hours of daylight. But>>
when the sun does set, it just goes down below the horizon a bit so it doesn't get "dark", at best it is dusky dark for a few hours, then it rises again. We really can't see the stars now, it doesn't get dark enough. My grandkids are coming to visit tomorrow, and we have to put aluminum foil in their bedroom window because it is just too light for them to sleep well. Up in Barrow, where I lived for a few years, the sun is up now for 24 hours. It is really tough to sleep. The weather is clear and in the low 70s---lovely. I feel so bad for all the east coasters who have so much rain.
