New region 13088 [S28W46] emerged on August 24 and continued to develop rapidly on August 25 when the group was numbered by SWPC. The region is currently not very complex magnetically, however, the rapid development spurred one M and multiple C flares. A major flare is possible. C1 flares: C1.8 @ 09:36, C1.4 @ 11:52, C1.7 @ 13:56, C1.5 @ 14:26, C1.9 @ 17:21 UT
New region 13089 [S22E58] emerged on August 24 and developed quickly on August 25 as the region was assigned its NOAA number.

Early on August 26 the magnetic delta is back. C1 flares: C1.0 @ 02:33, C1.3 @ 04:04, C1.4 @ 07:04, C1.2 @ 09:28, C1.4 @ 12:09, C1.7 @ 15:16, C1.5 @ 17:41, C1.4 @ 21:15 UT
