I went outside to have a cigarette around 10 after 10pm and was looking towards nw sky. saw a light moving at a steady speed, (not fast,no blinking lights)to the north. after watching about 5 seconds it grew brighter, then went back to brightness i observed at first,continuing to the n and gradually went out of site. i thought at first it could of been a plane, but there was no sound and as i said before, no blinking lights as an airplane or jet would of had. i probably would not of thought anything of it but about 3 seconds behind it was another one that did the same thing as the first one did. and about 3 seconds after that one, another one, then another, then another, i counted 7 or 8 in all, all turning brighter, then a little duller and headed towards north until not seen any longer. pretty odd.
