N 68.4 S 88.8
Region 12974 [S19W25] was quiet and stable.
Region 12975 [N13W24] is a complex region with multiple magnetic deltas. The region could produce a major flare. C1 flares: C1.8 @ 14:09, C1.4 @ 16:50, C1.5 @ 17:26, C1.8 @ 22:19 UT.
Region 12976 [N15W07] lost the magnetic delta and decayed slightly. An M class flare is possible.
Region 12977 [N21W38] decayed slowly and quietly.
Region 12978 [S17E52] was mostly quiet and stable and has M class flare potential.
Region 12979 [S19W03] decayed slowly and quietly.
Region 12980 [N08W40] decayed slowly and quietly.

Region 12974 [S20W38] decayed slowly and quietly.
Region 12975 [N13W37] saw consolidation in the central and eastern parts and less polarity intermixing. The region could produce another major flare as it still has a magnetic delta. C1 flares: C1.2 @ 01:40, C1.3 @ 08:10, C1.1 @ 10:17 UT.
Region 12976 [N15W20] was mostly quiet and stable. Numerous tiny spots emerged in the trailing spot section and there is some polarity intermixing in that area. An M class flare is possible. C1 flares: C1.8 @ 01:12, C1.2 @ 08:42 UT.
Region 12978 [S17E38] was mostly quiet and stable and has M class flare potential.
Region 12979 [S19W14] decayed slowly and quietly.
Region 12980 [N08W53] decayed slowly and quietly.

Region 12976 [N14W49] decayed in the trailing spot section and was mostly quiet. An M class flare is possible.
Region 12978 [S17E13] developed as new flux emerged in the intermediate spot section. Flare activity increased. C1 flares: C1.9 @ 08:35, C1.8 @ 16:16, C1.6 @ 20:00 UT
Region 12979 [S17W38]reemerged with tiny spots.
Region 12981 [S25E20] produced numerous C flares and may be capable of producing an M class event. C1 flares: C1.9 @ 12:54, C1.9 @ 16:44, C1.9 @ 20:08 UT
New region 12982 [S19E48] rotated into view on March 29 and was numbered by SWPC 3 days later as the region decayed slowly.
