Dear Collaborators,
Solar activity remains at a low level. The largest event since the last message was a C7.6 flare at 07:29 UT today produced by the target region NOAA 14136. 14136 also produced another three C-class flares (including a C6.5) during the period. It retains a beta- gamma/D-type sunspot group with decreasing the sunspot area and number of spots slightly. Today we will continue to watch this region. If possible, places also include NOAA 14143 (N25W60) in your field of view. 14143 has developed to a beta-gamma/D-type region and was the source of five low C-class flares. Note that a newly numbered region NOAA 14149 (N17E61, beta/D-type) was the source of three low C-class flares. Additional C-class flares are expected from various regions in the following 24 hours.
The position of NOAA 14136 on July 20 at 15:30 UT is:
N21W71 (834", 313")
