Summer Solstice Lightning
21 June, 2014

Professor Howard Cohen, founder of the AAC, forwards the following note and photo about the lightning storm on the evening of June 20:

Summer in Florida is not a friend to star gazers. Moist warm air rising over the Florida peninsular often brings extensive thunderstorms with abundant lightning, especially during afternoons and evenings. Last night was no exception. Active late evening thunderstorms brightly lit up north central Florida skies in the hours before midnight, 2014 June 20, about 7-8 hours before the June solstice (6:51 a.m., EDT June 21).
Most lightning was cloud to cloud including sheet lightning that strongly illuminated the northern and western horizons from this location. Photo taken from southwest Gainesville, Florida looking northwest toward the cities of Alachua and High Springs. Picture Taken: 2014 June 20, 11:36 p.m. EDT.
