CME on the way…Want to see the Northern Lights?
We have completed initial analysis of the CME associated with today’s X1 (NOAA Scale – R3) solar flare from Region 1944 (center disk) and have developed a forecast for a geoeffective event. Despite the CME not coming directly at Earth, a partial impact to the magnetic field that protects Earth is expected and a resulting geomagnetic storm as high as G3 (strong) levels is forecast to begin early to midday (UTC) on Thursday, 9 January (just after midnight to early morning hours EST).
It looks like we will have clearing late so you might want to set a 5 AM alarm! They also say that Friday night there’s a chance of aurora if we get clouded out! More aurora info at Space Weather.
