Many thanks to my good friend Mike Hansgen (K8RAT) who notes that another CME may affect the HF bands tomorrow. Spaceweather.com has posted an update:
"GREEN SKIES FOR ST. PATRICK'S DAY? Yesterday, a CME billowed away from the sun's western limb: SOHO movie. The massive cloud could deliver a glancing blow to our planet's magnetic field on March 17th, filling Arctic skies with green auroras just in time for St. Patrick's Day. NOAA forecasters estimate a 40% chance of geomagnetic storms on March 17th, increasing to 60% on March 18th as Earth passes through the CME's turbulent wake.
The incoming CME was propelled into space by sunspot AR2297. During the early hours of March 15th, the sunspot's magnetic canopy erupted in tandem with a nearby magnetic filament.["]
NOAA notes that there is a 50% chance this CME will cause geomagnetic storms, thus potential for unsettled HF band conditions.
