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).
