solar flareOne 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.
As seen in this Sept. 2 photo, highly active sunspot clusters on the sun have been producing a series of significant solar disruptions over the past two weeks.
