A special thanks to Sheldon Day for alerting me to this recent Coronal Mass Ejection (CME). Below is the text of the alert. The animation can be seen at spaceweather.com. This is a very fast moving CME and is directed at Earth. Expect a direct hit tomorrow before sunset. CMEs often cause ground currents and magnetic line movements, towards the earth when they impact. Protect your antennas, sensitive radio equipment, and your brain. There may be aurora borealis to be seen.
RADIATION STORM AND CME ALERT: 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 Earth other than to disturb HF radio transmissions at high latitudes. Energetic protons, which make up the bulk of the storm, were accelerated in our direction earlier today by shock waves in a CME racing away from the sun at about 1000 km/s (2.2 million mph). According to analysts at the Goddard Space Weather Lab, the CME itself will reach Earth on Nov. 28th around 14:23 UT (+/- 7 hours). Click to view an animated forecast track: [

The cloud could trigger geomagnetic storms when it arrives on Monday. High-latitude sky watchers should be alert for auroras.
The forecasting group at Goddard notes that no two spacecraft have yet beamed back concurrent images of the CME. This makes their estimates of the CME's speed and direction necessarily approximate. Stay tuned for updates as more data arrive.

SDF Number 330 Issued at 2200Z on 26 Nov 2011
IA. Analysis of Solar Active Regions and Activity from 25/2100Z
to 26/2100Z: Solar activity has been at low levels for the past 24
hours. A long duration C1 flare was observed at 26/0710Z in
conjunction with an eruptive filament channel near Region 1353
(N08W49). A full halo CME, first observed in C2 imagery at 26/0712Z,
was also associated with this event. The other regions on the disk
remained mostly stable and quiet throughout the period.
IB. Solar Activity Forecast: Solar activity is expected to be at
low levels with a slight chance for M-class events, for the next
three days (27-29 November).
IIA. Geophysical Activity Summary 25/2100Z to 26/2100Z:
The geomagnetic field has been at quiet levels for the past 24 hours.
At around 26/0840Z, signatures from the ACE spacecraft indicated
elevated levels of greater than 10 MeV protons. This increase was
associated with the eruptive filament channel, CME, and C1 flare
mentioned earlier. A greater than 10 MeV proton event at
geosynchronous orbit began at 26/1125Z. Max flux for this event,
thus far, was 54 pfu at 26/2055Z. This proton event was still in
progress when this report was issued.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to remain at predominantly quiet levels on day one (27
November). An increase to unsettled to active levels with a chance
for minor storm conditions is expected on days two and three (28-29
November). These elevated conditions are the result of the combined
effects of a coronal hole high speed stream becoming geoeffective
early on day two, and the arrival of today''s full halo CME late on
day two or early on day three.
