Automated message just sent to me from:

widely reported in the past 24hrs

Doubt if the cloud cover will allow me to have a good look out for it
tonight but I thought it was worth passing on to you all.

Activity needs to pick up first, too cloudy this evening in Sheffield
if it did pick up.


The red and orange alerts are for current conditions only. The "storm"
that generated the red alert has long since subsided.


An aurora forecasting site that has just come to my attention is this:

http://helios.swpc.noaa.gov/ovation/

It uses data from the ACE satellite about 1 hour "upstream" of us and
gives a very nice graphic of where the aurora is expected to be in about
45 minutes, together with a red line showing the southern limit of where
it would be visible on the horizon. At the time of posting this it
shows the auroral oval off the north coast of Scotland with it being
possibly visible from much of the Scottish Highlands.


If you have a smartphone, the "Europe" box has its own URL

http://helios.swpc.noaa.gov/ovation/Europe.html

and is a surprisingly small file size to download so you can keep track
of the aurora without having to fire up your PC.


The aurora alerts come from this site:

http://aurorawatch.lancs.ac.uk/

and this is currently showing a nice graph with red bars for the period
this morning when activity was at the "red alert" level.
