M4.5 solar flare from sunspot region 2158

Coronal Mass Ejection
Coronagraph imagery from SOHO/LASCO is still limited but a the beginning of what looks like an asymmetrical halo Coronal Mass Ejection is starting to become visible which suggest that this solar flare indeed produced a Coronal Mass Ejection that is at least partially directed towards Earth. The bulk of the CME looks to head north-east but there does seem to be an earth-directed component. More information on this will be posted later today as more imagery becomes available.

Solar Radiation Storm
We also issue a warning for a possible Solar Radiation Storm. The ammount of high energy protons near Earth are already elevated and we could cross the S1 threshold with this latest eruption.
