Also went up to the Pentlands and saw nothing. Some did though, there is at least one photo posted on Spaceweather from a bloke in Edinburgh that managed to see it here. He did say that it was very faint to the naked eye and the colours only really showed up on the camera.
Just seen a report on the UK MetO site saying that Hawaii has been hit by heavy rain. Reports of 27cm of rain !!! Thats over 10 inches in 24 hrs!! Never seen/heard of anything like it. Amazing
