Thursday evening around 8:40 pm, my wife and I were outside on our deck when she noticed a bright star, she thought. Wen I saw it I knew it was no star, twice the size of a normal star. Plus, in the north east sky, there were no stars of size. But, at that time, no stars were showing yet. I got my camera, Canon EOS T3i with 250mm stabilized lense and observed it thru that as I shot pics. It hovered motionless, looking to be several thousand feet above us. The moon was out, and the sun had just set, so the sky was dark as a background. We both saw random red pulses of lit from top and bottom, it seemed when my flash went off, I saw a red pulse. For 20 or more minutes we watched, my wife thru binoculars. As it got dark, it turned darker with the sky, with redder tints and simply faded into the darkness. I couldn't tell if it changed elevation, but my pictures might determine that. I am anxious to have the pics looked at, we did have another sighting and photo by a pilot that day, in the direct vicinity. I didn't learn of that until Friday the 29th. As we watched this orb or sphere, we both got dizzy and had one eye go fuzzy. My wife found a bug in hers and I had to set the camera down. It got better within 3 or 4 minutes. We are certain of what we witnessed, she a federal employee of 20 + years and I a Quality Assurance professional of 40 years, a professional observer. I wrote down the events within an hour and have copied the pictures to protect them from accidental damage. The hi resolution images are exciting.
