Forecasters at the NOAA Space Environment Center in Boulder, Colo., observed two dynamic areas of the sun, one of which has produced a coronal mass ejection, or CME, Wednesday morning at 3 a.m. EDT that appears to be Earth-directed. The forecasters are predicting a strong geomagnetic storm, G-3 on the NOAA Space Weather Scales, that should reach Earth on Friday, October 24. Satellite and other spacecraft operations, power systems, high frequency communications, and navigation systems may experience disruptions over this two-week period. Auroras visible in the lower 48 states are possible tonight and tomorrow.
