Three sisters ages 52, 46, 43 were visiting and spending the weekend together. at approximately 1:25 a.M. was gazing at the stars out the bedroom window and saw a large pulsating light hovering above the tree line of tall pines. she was unsure about what she was seeing and asked her sisters to look and confirm they could see the same. the object was observed for about a half hour and it appeared to have moved within that time a short distance northward direction from one tree to the next in that span of time. it was difficult to define an exact shape but had the appearance of something akin to a jellyfish shape dimming off and on in the water. it was too far to capture a picture with a cell phone in the night sky. this is being submitted real time if the object remains in the area of wilmot/new london nh.
