Solstice

21th June solstice marks the astronomical beginning of summer in the northern hemisphere and winter in the south. It also brings the north's longest day, the longest period between sunrise and sunset.

Next astronomical event:

A big, bright, beautiful Full Moon will rise at sunset on Sunday. Its exact full phase (June 23, 11:32 UT) will occur shortly before it reaches perigee, the closest point to Earth in the Moon's orbit, and make it the largest Full Moon of 2013. But such circumstances are not very rare. The full lunar phase falls near the Moon's orbit perigee about every 14 lunar months. That means the following Full Perigee Moon will be on August 10, 2014, the 14th Full Moon after June 23.
