Discussion of todays activity
June 12th is yet another active day on the Sun, no X-class flares where observed but three moderately strong M-class flares where observed from two active regions and also numerous C-class flares. The first M-class flare from today was an M2 solar flare from AR12087 and peaked at 04h21, it was however a short flare but looking at difference images there looks to be a CME associated with it but won’t be Earth directed due to the position of the region. The second flare was an M1.8 solar flare from AR12085 and immediately after followed by an M2 solar flare from AR12087. On the difference images of SDO imagery there is coronal dimming visible with material that’s being ejected, due to the lack of LASCO imagery we can’t determine if there is an Earthward directed part. EPAM monitor did show a rise in the low energy electrons so there might be an Earthward part but we will make a CME analysis once LASCO data is completed.

Discussion of Active Regions
This region still holds a minor delta spot in the central part of the region and is relatively stable, strong events are not expected M-class flares can’t be excluded.
Now that the magnetic configuration is now visible in better ways than this morning, we can conclude that a very strong delta structure persist in the central part of the region, it’s so compact that you can’t draw a line between those two magnetic zones. The images below will give you a better look:
Because of this strong delta structure, strong flares remain possible, X-class flare can’t be excluded.
