Subsiding radiation storm as new pair of CMEs taking place
A radiation storm that began on Nov. 26th when a magnetic filament erupted on the sun is subsiding. Nevertheless, the Earth-effects are just beginning. The same explosion 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 our planet today, on Nov. 28th at 17:21 UTC (+/- 7 hours).
The long duration S1 Level minor radiation storm is now over as the Proton levels have decreased to lower levels.
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 tonight. (SpaceWeather)
In the latest STEREO Ahead COR2 images you can see a pair of Coronal Mass Ejections (CMEs) and the second of these may have an Earth directed component. More information on this later today.
