solar flare

One of the largest solar flares on record was recorded by the NOAA Space Center in Boulder, Colo., at 1:40 p.m. EDT on Sept. 7. Forecasters are predicting significant solar eruptions over the next few days.

Electric power systems, high-frequency communications, low-frequency navigation systems and spacecraft operations may experience disruptions over the next two weeks.

LASCO (Large Angle Spectrometric Coronagraph) is able to take images of the solar corona by blocking the light coming directly from the sun.
