POWERFUL SOLAR FLARE ERUPTS Sept. 9, 2005 ? Forecasters at the NOAA Space Environment Center in Boulder, Colo., continue to observe significant flares on the sun Friday in NOAA sunspot Region 808. This is the same region that yielded a powerful X-17 flare on Wednesday—R4, severe radio blackout, on the NOAA space weather scales. NOAA cautions satellite and communications groups are already experiencing problems due to this activity. Other agencies impacted by space weather are at increasing risk for service disruptions. This includes other space activities, electric power systems, high frequency communications and navigation systems such as global positioning systems.
