at 2:45 am on may 28, 2015 an orange glow out my north and south windows woke me. I checked outside and saw it coming from the south. Heavily overcast sky after weird weather so I assumed it to be a weather phenom. a dim flash, (like sheet lightning), was pulsating at a little less than a second & this continued as long as the glow was around. (at least one and a quarter hours) at 4:00 am regular dark night resumed. all just disappeared. sheet lightning doesn't come that consistently. it is more eratic. The glow had seemed to emanate (sp) from a large area low in the south sky and then had moved slightly to the southwest and then back to first position. no more sleep!
