It took a little while but the sunspot group that we told you to watch out for yesterday has woken up! Sunspot region 2158 was the source of a long duration M4.5 (R1-moderate) solar flare that peaked today at 00:29 UTC.
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.
ALERT: Type II Radio Emission Begin Time: 2014 Sep 09 0019 UTC Estimated Velocity: 999 km/s
ALERT: Type IV Radio Emission Begin Time: 2014 Sep 08 2340 UTC
SUMMARY: 10cm Radio Burst Begin Time: 2014 Sep 08 2349 UTC Maximum Time: 2014 Sep 08 2352 UTC End Time: 2014 Sep 08 2359 UTC Duration: 10 minutes Peak Flux: 370 sfu Latest Penticton Noon Flux: 164 sfu
