M1.4 solar flare with earth-directed CME

A huge surprise at 05:26 UTC today as unimpressive sunspot region 2974 
produced a long duration M1.4 solar flare.

It became quickly obvious based on SDO imagery that this event likely 
was eruptive. Moments later, the confirmation of both Type II and IV 
radio sweeps added even more confidence to this early conclusion. Now 
that we have SOHO/LASCO coronagraph imagery we can take a look at the 
coronal mass ejection and see if it is aimed at Earth. We see an 
asymmetrical full halo outline but most of the ejecta is heading west. A 
faint halo outline is visible which does mean aglancing blow is possible 
on Monday, 28 March. The NOAA SWPC has yet to publish an official 
forecast but we do not expect geomagnetic storming from this event. The 
earth-directed portion of the plasma cloud is faint and should only 
cause limited geomagnetic disturbance at high latitude locations. 
Nonetheless something to keep an eye on for high latitude sky watchers.
