Dear Collaborators,
Solar activity has returned to low levels. The largest event since the last message was a C3.6 event at 06:00 UT today produced by NOAA 13213. 13213 just emerged today and has been classified as a beta-gamma/C-type sunspot group. This region is the most productive and has produced more than 10 flares. Today the target shall switch to this region. Yesterday's target region NOAA 13211 (S17W64, beta/D-type) produced only a C1.5 flare in spite of an increasing magnetic complexity. Moreover, newly-emerged regions NOAA 13216 (N24E60, alpha/H-type) and NOAA 13214 (N10E26, beta/D-type) produced a few low-C flares. Further low C-class activities are expected and high C-class flares are very likely in the following 24-hour period.
The position of NOAA 13213 on 7-Feb-2023 12:30 UT
N29E06 (-89", 565")
