NOAA ISSUES SPACE WEATHER WARNING; POWERFUL SOLAR FLARE ERUPTS;
KATRINA COMMUNICATIONS MAY HAVE BEEN AFFECTED
Sept. 7, 2005 Forecasters at the NOAA Space Environment Center in Boulder, Colo., Wednesday observed one of the largest solar flares on record at 1:40 p.m. EDT. The forecasters are predicting significant solar eruptions in the coming days. Agencies impacted by space weather storms may experience disruptions over the next two weeks. These include spacecraft operations, electric power systems, high frequency communications and low-frequency navigation systems.
"This event created a complete blackout of high frequency communications on the daylit side of Earth, which included the entire U.S. and basically anywhere the sun was shinning at this time," said Combs. "Communications used by emergency services along the Gulf Coast may have experienced problems due to this flare. Low frequency navigation systems may also have experienced a period of significant degradation," he added.
