M-class flares 3-4 May, 2022

M5 flares 3-4 May, 2022
M-class flares 3-4 May, 2022
published: Friday, May 06, 2022 18:13 UTC

Region 3004 produced an M5.7 flare (R2-Moderate Radio Blackout) at 4:59 am EDT (04/0859 UTC). Region 3004 is the most notable sunspot group currently present on the visible solar disk and it exhibited some additional growth overnight. Another M-class flare (M5.3) occurred from just beyond the southeast limb on 3 May at 8:19 pm EDT (04/0019 UTC). Additional M-class flares remain likely, with a chance of X-class activity, due primarily to the combined flare probabilities of Region 3004 and the as yet, unidentified source region of M and X-class flare events from the southeast limb.
