Here's a note from the President of the Astronomy Club on Bainbridge Island, where the Ritchie Observatory is located:

Two recent Coronal Mass Ejections may give us an aurora on the 24th or 25th. The clear sky clock for the Ritchie Observatory says we can expect to see some sky the evening of the 24th (although tonight the 23rd doesn't look too promising). Take a look to the north each night!
