Space Weather News for Nov. 20, 2003
http://spaceweather.com A coronal mass ejection swept past Earth during the early hours of Nov. 20th and sparked bright auroras over northern parts of the United States. At the time of this writing (1600 UT or 11:00 a.m. EST) a strong geomagnetic storm is in progress. The interplanetary magnetic field near Earth has tilted sharply south--a condition which promotes geomagnetic activity. If this condition persists, auroras are possible at low latitudes tonight. The source of this space weather is sunspot 484--one of the trio of big sunspots that caused intense solar storms last month. Indeed all three of those active regions are back on the Earth-facing side of the sun, so more solar activity is possible in the days ahead. Visit Spaceweather.com for more information and pictures of today's auroras. __________________________________________________ _____ -Sam Wormley http://edu-observatory.org/eo/aurora.html |

The NOAA numbers do not specifically refer to a "sunspot" but to an active region. In any event, NOAA 10484 has been renumbered as 10501, since that appears to happen on each solar rotation. -- David W.

I'd say! Here in Central North Carolina (at 7:10PM EST) they are brighter
than they were a couple of weeks ago. Awesome!! To say the least. "Sam Wormley" wrote in message ...
