SpaceWeatherLive Solar Activity Update

December 7, 2013 - 14:15 UTC

Solar activity increased to moderate levels thanks to an M1.2 solar flare from Active Region 1909. The solar flare took place at 07:29 UTC. An Type II Radio Emission was observed indicating the launch of a Coronal Mass Ejection. The STEREO spacecrafts confirm that a CME was launched. SOHO/LASCO imagery is still lagging very much behind which makes it unable for us to analyse if the Coronal Mass Ejection has an Earth-directed component.

EPAM showed a sudden rise at 1:00 UTC which is still under investigation but another slow rise started after the M1 flare. This indicates that the the CME from the M1 flare could very well have an Earth-directed component. However, it is vital that we get SOHO/LASCO imagery to make a final analysis. Below a video of the event:





What can we expect in the upcoming 24 hours?

Active Region 1909 is a group with a very simple magnetic layout and more strong flares are not to be expected from it.


M-class flare probability: 5% chance

X-class flare probability: 1% chance
