Putting out the bins at 07.10 looking up at a clear dark sky decided to get my glasses(short sighted).I first saw a bright dot travelling from north to south saying to myself thats a satellite.Next another one 3 seconds later and then for about 40 minutes in sequence a number of travelling dots(as high as a plane would travel)After every 5 or so there would be two dots travelling one behind the other and this happened about 3 times. I have never seen this before and just wondering what these could be , They didnt seem like planes too close together, satellites maybe, birds at that height i dont think so, very strange.
