From cdeehr at gi.alaska.edu Sat Jan 1 16:11:53 2005 From: cdeehr at gi.alaska.edu (Charles Deehr) Date: Sat Jan 1 16:25:49 2005 Subject: [gse-aa] Auroral Alert Message-ID: <000001c4f068$11cb7cf0$ec1be589@Forcastle> 1) Effects from a high speed stream in the solar wind are reaching Earth this evening. Aurora should be visible over most of Alaska, and as far south as the Canadian border across the northern US. 2) An X class flare just east of the central meridian of the sun occurred on New Year's Day at 0030 UT. The effects of this flare should arrive late on Jan 2nd UT. This means that auroral activity will be active to high during the period January 1-3. The aurora may reach as far south as WA, WY, MN, IL MI, NY, etc. and Northern Europe. Note that the aurora could be visible on the northern horizon from points farther south, especially around local midnight. Tasmania and Southern New Zealand should also be on the alert.

The effects of this flare should arrive at Earth on the 16th of January. Ordinarily, this small flare would not produce much auroral activity, but this time it is on the solar central meridian (facing Earth) and the shock will arrive simultaneously with a high speed solar wind stream. Look for enhanced auroral activity at least in Alaska, southern Scandinavia and Canada, and the Northern US perhaps starting late on the night of the 15th and certainly by the 16th.

The effects of the flare are already reaching Earth. Extensive auroras should occur on the night of the 17th, if not sooner. If it is clear in your area, check the night sky. This includes US, Europe, New Zealand, Tasmania and of course Russia, Alaska, Canada and Scandinavia.

The effects of this event should reach Earth by 5 am on the 21st gmt. This means that there could be significant auroral activity in all areas on the night of the 20th/21st local time. This could extend for 2 more days. See the movie at http://gse.gi.alaska.edu/recent/javascript_movie.html Dr. Charles Deehr, Prof. Emer. Phys.

The southern edge of the aurora should be visible from England, Northern Europe, and middle USA. Dr. Charles Deehr, Prof. Emer. Phys.
