GEOMAGNETIC STORM WARNING: A large hole in the sun's atmosphere is facing Earth and spewing a stream of solar wind in our direction. NOAA forecasters say there is a chance of moderately-strong G2-class geomagnetic storms when the gaseous material arrives on Sept. 28th. The last such storm in early September produced auroras visible in many northern-tier US states. Visit today's edition of Spaceweather.com for more information and forecasts.
