Region 13067 [N19W40] was quiet and stable.
Region 13068 [S16W27] decayed slowly. An interesting C6 flare was recorded peaking at 17:08. The flare triggered a filament eruption to the north of the region and an EIT wave was observed expanding towards the north and northeast. It is uncertain if there was a CME associated with this event, but if it was it could be headed at Earth. C1 flare: C1.3 @ 02:47 UT.

New region 13071 [S18E58] rotated into view late on August 1 and was numbered by SWPC 2 days later.

Spotted regions not observed (or interpreted differently) by SWPC:
New region S7743 [N21W03] emerged with tiny spots before noon, then decayed leaving only one spot 8 hours later.
New region S7744 [S24W12] emerged with tiny spots.
New region S7745 [S33W15] emerged with tiny spots.
New region S7746 [S22E33] was observed with a tiny spot in an old plage area.
