Space Oddity!!
@EnolaGaia, you may be able to explain this one. Just happened. 30 minutes after sundown I'm skygazing westward and I see my first satellite of the evening. Just a really dim steady mover like you'd expect under a near full moon. Then within seconds it glows brighter and brighter and suddenly I see there are now
two points of bright light in tandem right next to one another and the shine gets brighter and brighter for about ten seconds then slowly dims over another 20 seconds and disappears like you'd see one go behind the shadow of the earth.
I was speculating it must be a conjunction of two separate birds and that they would drift apart in time and vector, but they stayed exactly parallel and glowed and dimmed together, as if they were joined together as part of one structure.
There is no ISS here in Adelaide tonight. I'd just checked before I went outside. I thought when it started to get really bright that it was the ISS and there'd been an error by NASA until that second light appeared right next to the first like they were two ends of a barbel structure. No ISS. This was a very different satellite. I know my space cans. This thing I'd never seen before.
I also considered it must be an iridium and it would rotate around and get back into glow again as they are wont to do spinning about. It never reappeared. I followed the trajectory it would have taken for five minutes and nada.
Weird. WTF?
