SOLAR ACTIVITY: On Sept. 4th around 1600 UT, a magnetic filament erupted, 
hurling a bright coronal mass ejection (CME) off the sun's northwestern limb. 
Today's edition of http://spaceweather.com features a close-up view of the blast 
from NASA's Solar Dynamics Observatory. The CME is not expected to hit Earth. 
Nevertheless, auroras are possible in the nights ahead.  A solar wind stream 
flowing from a coronal hole is heading our way, due to arrive on Sept. 5th or 
6th. NOAA forecasters estimate a 50% chance of high-latitude geomagnetic 
activity when the solar wind hits. With the approach of northern autumn, Arctic 
nights are getting dark again--dark enough to see the Northern Lights.  People 
in Alaska, Canada and Scandinavia should keep an eye on the night sky this 
weekend.
