Dave Gradwell in Birr, Co. Offaly just called Astronomy Ireland (5:36pm)
to say there is a major aurora in progress! There was a corona overhead!
Keith Geary in Cavan just sent a TEXT saying RED aurora overhead. I can
see it from our Shop window in the brightly lit Butterly Business Park
in Dublin 5! Heading to country-side soon!
Checking the web sites and emails confirms a massive geomagnetic storm
is in progress and has been since 8am (been a little too busy in the
aftermath of our extremely successful Astro-Expo to be checking as
regularly as I usually do! see website for Astro-Expo report by the way,
with photos!).
The aurora was caused by a CME (coronal mass ejection) from sunspot
group number 484 that has survived a complete rotation around the back
of the Sun and is nicely on view again (I saw it from the office just
before the Sun set in a pair of 10x50s fitted with AstroSolar filter).
The CME happened on Nov. 18.
