Solar activity reached major levels on February 1 as Active Region 4366 (N14E40, beta-gamma-delta) produced a series of M-class flares followed by a major X1.0 flare at 12:33 UTC.<\/p>\n

Activity began intensifying late January 31 with several C-class flares ranging from C2.8 to C7.8 between 16:00 and 22:18 UTC.<\/p>\n

By early February 1, the region produced a steady sequence of M1.7, M1.0, and M1.9 flares, followed by M6.6, M2.4, and M6.7 before X1.0, suggesting rapid magnetic reconfiguration and increasing magnetic shear within Region 4366\u2019s delta-spot structure as it rotates toward the central solar meridian.<\/p>\n
