Was up at 4.30 this morning (gip from shoulder and knees) and went downstairs to take paracetamol and make cup of tea. Stuck my head out of the back door to see if it was clear sky - beautiful starry vista and I was just thinking "wonder if it's too early to see any satellites", and bugger me there was one. Looking at
Heavens Above a few mins later identified it as probably
Geosat on a NNE/SSW orbit. If I'd been a bit quicker, could have used the Live Sky view.
