From cdeehr at gi.alaska.edu Wed Sep 20 11:50:24 2006 From: cdeehr at gi.alaska.edu (Charles Deehr) Date: Wed Sep 20 11:53:06 2006 Subject: [gse-aa] Auroral Alert Message-ID: <002001c6dcee$06e1b420$ec1be589@Forcastle> We expect that the coronal hole on the sun that is facing Earth will lead to some increase in auroral activity on the coming weekend. Our predictions of this increase in auroral activity have been one day early for the past two solar rotations. Aurora watchers should check the sky on Friday Sept 22, but be aware that the high speed stream producing the activity may be one or two days late. We expect this activity to be visible over Canada, Alaska, the northern tier of states in the USA, Scandinavia, and northern Russia. It may be visible low on the southern horizon from Tasmania and southern New Zealand. (Kp 4 to 6). Dr. Charles Deehr, Prof. Emer. Phys.
