It was a little after sunset and I noticed a star at an Altitude of about 90 degrees. It wasn’t moving and it looked like any other star, but all of a sudden it started to get dimmer. I thought maybe a cloud was passing over, and there were a few small clouds around, but none I could see directly covering this particular star. Apart from a few small clouds the sky was very clear. I think I watched for maybe another 30 – 60 seconds as this star totally disappeared. I’m thinking whether it could have been a geostationary satellite, but I only know of these satellites to hover over the equator, and I’m nowhere near the equator. It would have been a few years ago now, and I’m still wondering what it was. Can anyone tell me if a geostationary satellite could hover over a location apart from the equator or whether it could have been something else?
