A note from our eye on the sky, Bill Westphal:

The Summer Solstice occurs this Friday, June 20 at 4:59 p.m. At this moment, The Sun reaches its most Northern point in its apparent path around the Earth. This marks the beginning of Summer in the Northern Hemisphere and Winter in the Southern hemisphere.

Also, Wednesday June 18 is the Full Moon.  If you’re watching the Moon rise in the East at 8:36 PM you may be lucky enough to witness the Solstice Moon Illusion.  Read an interesting article about it here from NASA:
