A solar event near the limb took us by surprise. The effects of this event
were first felt early on the 23rd GMT, but the ejecta from the sun arrived
just now (5:30pm Apr 23 GMT).  

Tonight there will be aurora over the northern tier of the US, Northern UK,
Southern Scandinavia, and Southern Alaska.  Observers in Southern New
Zealand and Tasmania should watch the sky tonight, if the activity proves to
be long-lasting.
