Active Region 1936

SpaceWeatherLive Solar Activity Update

Solar activity increased to high levels thanks to a long duration M6.4 solar flare (R2 - moderate) solar flare from Active Region 1936. The solar flare peaked at 21:58 UTC. This region is in a good position for an Earth-directed Coronal Mass Ejection but there are currently no LASCO or STEREO images available to confirm a CME launch. More updates will follow later.



Update 0:05 UTC:

The strength and duration of the flare make it likely that the flare produced a Coronal Mass Ejection but there isn't any imagery available yet to confirm this. No radio sweeps were reported. Here is a video of the event:

Active Region 1936 just erupted with an M9.9 (R2-moderate) solar flare. It peaked at 18:52 UTC. This region is already rotating towards the western limb but if this flare produces a CME, it might have an Earth-directed component. A direct hit will not be possible anymore. There will also be a risk that for a space radiation storm.




M6.4 solar flare CME:

Quick recap of yesterday's M6 solar flare: that flare produced a very weak CME which was hardly visible on LASCO. No activity is to be expected from it.

A large solar flare (likely X-class) from behind the western limb caused a sudden jump in the primary >10MeV protons. It likely came from region 1936. It is the source of the S1 space radiation storm that we currently experience. The large solar flare is clearly visible on STEREO A imagery. The flare was associated with a large eruption which could even be seen on imagery from SDO. The resulting CME will not be Earth-directed because this is a far side event. The protons are however able to reach Earth thanks to the Parker spiral.

An impressive Coronal Mass Ejection (CME) was launched which shows up as a asymmetrical full halo CME on imagery from both SOHO/LASCO (not in this video) and STEREO B COR2. The CME is however heading away from Earth, as this was a farside event.
