We were staying in a cabin in Cherryville. On Thursday night we were stargazing and watching what I think were satellites track across the Eastern sky, one every ten minutes or so on basically the same path. About 9 pm we both noticed a pop or flash of light just above the trees about 40 feet from our location. We both saw the light and looked to the spot, about three seconds later a second flash was seen about ten feet from the first.We discussed what we saw and after a few minuets sat back down in our chairs. At that time we saw that a large portion of the South East sky was completely blocked out. WE had just been looking at the stars there and now a dark grey mass was blocking out the stars. The edges were uneven like a cloud. The night was completely clear except for this area that went dark after we saw the flashes of light.The obstruction never drifted away or moved at all. From time to time I checked that portion of the sky and about an hour latter the view was back to normal.
