Supermoon comes just days after summer solstice
J. Alex Knoll
Thursday, June 20, is Midsummer’s Night, the shortest night of the year, with barely nine hours of darkness. Then, at 1:04am Friday, the sun reaches its northernmost position above the earth, marking the astronomical beginning of summer for us in the Northern Hemisphere. It is our longest day, with more than 14 hours 54 minutes of sunlight.
