White/bluish lightbulb flashing strobe lights in rural skyWe awoke to a white blue flashing light in Southeastern sky within 1/2 mile from the village. At first thought it was lightning or a transforming blowing up. Then, after calling power company and disqualifying lighting continued to watch the repeating pattern for 2 hours. It was a strobe light pattern and has a slight blush cast to it. It cycled about every 15 sec with 4-6 small pulses and then one big light bulb flash then cycled again. Although the origin was behind the tree line -- probably 1/4mile or less from our house the big light bulb flash lit up our whole backyard. That went on for over an hour very intensely. We were going to get in the car to find it but felt extremely frightened...did not want to encounter something. This is a rural area with no towers or even few street lights or anything that could have explained it. Our dog was extremely upset during this time.
