Bright light appears and then fades as it crosses the sky.Staying at the "Mid Trail" resort which is halfway through the Cabot Trail and adjacent to Pleasant Bay.The sky was perfectly clear.I was laying outside on the patio with a blanket and pillow just watching the stars.I saw several planes fly behind the mountains nearby and a couple of satellites fly by.At 1am directly above me a round light appeared as though it just phased in. It was nearly 3 times brighter than any star in the sky including Venus. Once it peaked its brightness it moved as slow as a satellite does from West to East across the sky. As it moved it began to fade in brightness until it looked much like a normal satellite does. It travelled for another 4 or 5 seconds then just simply disappeared.I have seen many satellites and planes over the years as well as meteors and this was like nothing I have ever seen before.((NUFORC Note: Flare from Iridium satellite. PD))
