I was sent a link to this site last night that looks pretty good for giving predictions on the Aurora. It stated that they predicted an activity level of 4 on Thursday night and they even have a graph to show what a level 4 activity level translates into. As you can see from the map - the aurora oval was much higher than all the press coverage here was suggesting.
But Simon, who was on my Skye workshop last December is currently up in the far north of Scandinavia, so he should have a much better chance than any of us living here in the UK will by the looks of it.
Good luck Simon! :-)
