A solar radiation storm is in progress around Earth. At the moment, the storm is classified as minor, which means it has little effect on our planet other than to disturb HF radio transmissions at high latitudes. Bigger effects, however, may be in the offing. The same explosion on Nov. 26th that caused the radiation storm also hurled a CME into space at about 930 km/s (2 million mph).
According to analysts at the Goddard Space Weather Lab, the CME will reach Earth on Nov. 28th at 17:21 UT (+/- 7 hours). Click to view an animated forecast track:
The impact of the cloud could trigger a geomagnetic storm. Indeed, NOAA forecasters estimate a 58% chance of severe storming around the poles when the CME arrives. High-latitude sky watchers should be alert for auroras after nightfall on Monday
