Data from my magnetometer shows that the CME hitting Earth at the moment may cause aurorae over ireland tonight

Dave your magnetometer is not lying. The KP index just shot up to 10. Cloudy here but if anyone has clear slots, go outside and check for aurora now!!

I went straight to the UK Met sat image page after reading Daves post.

Drove from work in Galway to Charlestown almost 60 miles, was even watching Sat 24 for breaks but total cloud cover while high above the KP was at 8, but did anyone see the photos on SP? Not as impressive as one might have thought for such a severe storm with no Corona at zenith, one guy said the images need a long exposure to see colour while another photo just showed a bright green horizon, so I'm not feeling too upset today but annoyed like everyone else at the time.

Of course was clear the previous night and even went up to Lough Talt to photo M45 and Jupiter, KP still high so maybe it will clear tonight

Yep think it was clouded out here altogether.
BE careful reading the Kp index as it is a logrithmic average taken from mostly high latitude magnetometers. So a Kp of 8 may not necessarily mean aurorae over Ireland. The variations that I was getting while very obvious were not HUGE hence my retisence in my original post and why I say "may cause".
Also it was the wrong polarity (+) to really interact with the earths magnetic field. What we were seeing was the Earths mag field being "squashed" and "stretched".
Anyway I think I must have ben the only one to "see" it from ireland as I watched the laser pointer on my magnetometer dance all over the place.

heres the plot .... the normal diurnal pattern is a slow undulating "S" patern. The individual spikes are local interferences but the storm is obvious toward the right of the graph




My vlf monitor also showed some activity but this is still being calibrated so I wouldnt trust its data yet

Nothing in the midlands on Friday night, clouded out with a few breaks but I didn't spot anything.

Hi Guys, I would love to see it from a Northern latitude. I note Icelandair are running packages for a 3 night stay with a trip to a dark site location on 1 night out of the UK for under £400 which sounds good. Any advice on where and when would be a good location to see it?
