Coronal mass ejections (CMEs)
January 15: At least two fully Earth  directed CMEs were launched during the 
day. The first one was associated with a  long duration M8 event in region 
10720 after 06h UTC. This was a fast and large  CME and is likely to impact Earth 
during the latter half of January 16 and cause  major to very severe 
geomagnetic storming. The second significant CME was  launched during the the X2 long 
duration event in region 10720 late in the day.  Again this was a large and 
fast CME and will likely reach Earth on January 17  and extend the disturbance 
already in progress.
 
Forecast
The geomagnetic field is expected to be quiet to unsettled  during the first 
half of January 16. Sometime during the latter half of the day  a CME is 
likely to impact Earth and cause major to very severe geomagnetic  storming. This 
geomagnetic storm will continue on January 17 and be extended by  another CME 
reaching the Earth sometime during the day. Further major CMEs are  likely from 
region 10720 over the next days and the geomagnetic field is likely  to 
remain at storm levels for several days. Radio propagation over polar and  near 
polar paths will become severely degraded due to the storm and the proton  levels.
