Region 13001 [S32W65] was quiet and stable.
Region 13004 [S13W57] decayed slowly and was mostly quiet. There is still a weak magnetic delta in the southeastern part of the main penumbra and a major flare is still possible.
Region 13006 [S30E31] gained area and still has a magnetic delta in a small central penumbra. An M class flare is possible. C1 flares: C1.0 @ 07:39 UT

Spotted regions not observed (or interpreted differently) by SWPC:
S7542 [S15W45] was quiet and stable.
S7550 [S18W29] was quiet and stable.
S7551 [N28W01] was quiet and stable.
New region S7552 [S24E79] rotated into view before noon, this is probably old AR 12991. C1 flares: C1.4@ 13:07 UT (this flare was incorrectly attributed to AR 13004 by SWPC). The region produced a C6.3 flare at 03:53 on May 8.
New region S7553 [N17W62] emerged with several spots late in the day.
New region S7554 [S29E02] emerged with a tiny spots.

Region 13001 [S32W79] was quiet and stable.
Region 13004 [S13W71] decayed further and was mostly quiet. The region lost the magnetic delta but could still produce an M class flare. C1 flares: C1.7 @ 00:41, C1.8 @ 07:47, C1.0 @ 09:06 UT
Region 13006 [S30E18] was mostly quiet and stable. There is still a magnetic delta within the largest penumbra and an M class flare is possible.
New region 13007 [S24E72] rotated partly into view on May 7 with the trailing spots becoming visible on May 8 when the region was numbered by SWPC. The region could produce a minor M class flare.

Spotted regions not observed (or interpreted differently) by SWPC:
S7553 [N17W79] developed early in the day, then began to decay. Note that SWPC thinks this AR 13005, a region that was located 3 degrees further north.
New region S7555 [N02E32] emerged with tiny spots and is likely an SC24 group.

Region 13006 [S30W33] has many small spots spread over a large area, however, none of them have mature penumbra. Actually the region could be splitting into 2 separate regions. Further C class flaring is likely and there is a chance for a minor M class flare as well. C1 flares: C1.6 @ 05:37, C1.2 @ 10:10, C1.7 @ 15:11 UT
Region 13007 [S23E18] has many spots and currently only a small magnetic delta. An M class flare is possible. C1 flares: C1.3 @ 13:02 UT

Region 13009 [N14W37]decayed slowly and quietly.
New region 13010 [S14E76] rotated partly into view on May 11 and was numbered the next day by SWPC as all spots became visible. There may be a magnetic delta in the southeasternmost penumbra, however, we will have to wait until that spot rotates into better view to be certain. C1 flares: C1.6 @ 17:59 UT

Region 13006 [S30W47] decayed losing many small spots and was mostly inactive.
Region 13007 [S22E07] is slowly becoming better organized. Area increased while some small spots disappeared. The magnetic delta disappeared as well and only small C flares were produced. The region has M class flare potential. C1 flares: C1.8 @ 07:42 UT

Region 13006 [S29W62] decayed further and could become spotless before rotating out of view. C1 flares: C1.8 @ 12:19 UT
Region 13007 [S22W08] lost area in the trailing spot section while area increased in the leading spot section. The region gained spots and remained mostly quiet. Despite the high number of spots there is only weak polarity intermixing near the center of the region. C1 flares: C1.6 @ 05:15 UT
Region 13008 [N16W06] decayed slowly and quietly.
Region 13010 [S14E49] decayed as all but one of the larger spots lost mature penumbra and fragmented into smaller spots.
Region 13011 [N17E50] was quiet and stable. There seems to be some confusion internally at SWPC about this region as the one responsible for flare analysis assigns flares in AR S7569 to AR 13011.
New region 13013 [S28E29] was first observed with spots on May 11 with SWPC numbering the region 3 days later as slow development occurred.

Spotted regions not observed (or interpreted differently) by SWPC:
S7568 [N13E13] was quiet and stable.
S7569 [N13E67] produced several C flares and appeared to be decaying slowly. C1 flares: C1.5 @ 03:59, C1.8 @ 14:27 UT
S7570 [N22E68] was mostly quiet and stable.
New region S7571 [N01W28] emerged with tiny spots. This is an SC24 group.
