Comment from Belgium:
COMMENT: Solar activity increased during the period due to a new region
rotating around the East limb in the Northern hemisphere. This new region
produced thirteen B-class flares among them the largest B8.9 flare peaking
at 14:59 UT yesterday. No earth-directed coronal mass ejections (CMEs) were
observed in available coronagraphic imagery. The greater than 10 MeV proton
flux was at nominal levels. Solar activity is expected to be at low levels
with a significant chance for C-class flare.
Solar wind speed gradually increased as expected from around 320 km/s to
around 490 km/s during the period under the influence of positive polarity
extension of the northern polar coronal hole. Total magnetic field varied
from 2 to 12 nT, while Bz component varied from +10 to -9 nT. Geomagnetic
conditions were mostly quiet until 06:00 UT today, then both local index
(Dourbes) and planetary (NOAA) reached the value K = 3 due to the enhanced
solar wind speed. Mainly unsettled and active geomgnetic conditions can be
expected today and tomorrow.TODAY'S ESTIMATED ISN : 027, BASED ON 14 STATIONS.

SOMETHING IN THE OFFING: Just behind the sun's eastern limb, a hidden sunspot is crackling with solar flares. Yesterday, NASA's Solar Dynamics Observatory recorded this movie of hot plasma leaping over the edge of the solar disk:

In the past day alone, Earth-orbiting satellites have recorded almost a dozen B-class solar flares. Such relatively weak flares would never be mentioned during Solar Max, but any flare is remarkable during the current period of deepening Solar Minimum. In the next day or so, the underlying sunspot will be revealed by solar rotation, and we shall see if it has potential for stronger explosions.
NOAA recently recorded a C2 at 1821 UT today, May 23, 2018.
This most likely was from the new sunspot that is now rotating into view.
Nevertheless, The Sun Today has photos showing that another new active region is now present in the West (right). And it looks like a Beta. In fact, it is even bigger than AR2710, which is now showing signs of decay.
