Solar Storm Reaches Earth; More Activity Expected
Boulder - Oct 27, 2003 The geomagnetic storm predicted by the NOAA Space Environment Center hit the Earth's magnetic field at 11:30 a.m. EDT on Friday. It is currently at the G-3 level on the NOAA space weather scales - the highest being a G5. The solar particles and energy produced as a result of this storm can produce effects for many hours, so there is a possibility of seeing the aurora borealis or northern lights in the northern latitudes Friday night. Two very large sun spot regions continue to maintain their size and magnetic intensity. There have been three major flares in the last 24 hours, which caused considerable disruption of high frequency communication. More large flares are expected in the next few days. "So far this storm is materializing as expected," said NOAA space weather forecaster Bill Murtagh. NOAA forecasters predicted the onset of the magnetic storm to occur midday Friday. The magnitude the of G-3 level storm is also in line with NOAA predictions. NOAA thus far has not received any reports of the storm's effects. NOAA is dedicated to enhancing economic security and national safety through the prediction and research of weather and climate-related events and providing environmental stewardship of the nation's coastal and marine resources. NOAA is part of the U.S. Department of Commerce.
