From cdeehr at gi.alaska.edu Wed Jul 27 15:54:18 2005 From: cdeehr at gi.alaska.edu (Charles Deehr) Date: Wed Jul 27 15:55:12 2005 Subject: [gse-aa] Auroral Alert Message-ID: <000001c59306$86d8f720$ec1be589@Forcastle> There is an active region on the sun that has been sending significant shock waves into interplanetary space facing away from Earth for the past two weeks. This active region, AR 0786, is now on the east limb of the sun and will be in sight of Earth for the next two weeks. The effects of some of the latest events that occurred while AR 0786 was coming around the east limb are reaching Earth now. Because it has been facing away from Earth, these effects were less than what we expect for the coming two week period. We are already seeing disturbances as far equatorward as the US Canadian border and southern Scandinavia (Kp=4), so there should be auroral activity at lower latitudes during the next two weeks as this active region faces Earth. We will try to alert you if there are some large events. In the meantime, watch the poleward night sky. Dr. Charles Deehr, Prof. Emer. Phys.
