Solar flaring activity has reached moderate levels, with several C-class flares and one M-class flare recorded over the past 24 hours. The largest flare was an M2.3 flare, peaking at 10:00 UTC on December 4. It was associated with an active region (AR) behind the east limb (S09E89), which is currently rotating onto the solar disk.There are currently eight numbered active regions visible on the solar disk. SIDC Sunspot Group 323 (NOAA Active Region 3906; beta-gamma) is the largest and most complex region on the disk but has only produced C-class flares in the past 24 hours. It is expected to rotate over the west limb within the next few hours, along with SIDC Sunspot Group 322 (NOAA Active Region 3905; beta-gamma), that was inactive over the past 24 hours. Low flaring activity was also produced by SIDC Sunspot Group 330 (NOAA Active Region 3916; beta). Other regions on the disc have simple configuration of their photospheric magnetic field (alpha and beta) and have not shown any significant flaring activity. Solar flaring activity is expected to be at low levels over the next 24 hours, with C-class flares very likely and a chance of M-class flares.
No Earth-directed coronal mass ejections (CMEs) have been detected in the available coronagraph imagery over the past 24
hours.
A positive polarity mid-latitude coronal hole (SIDC Coronal Hole 60) started to cross the central meridian.
The greater than 10 MeV GOES proton was below the 10 pfu threshold over the past 24 hours. It is expected to remain below the threshold level over the next 24 hours. There is a small chance that the proton flux may increase in case of strong flaring from SIDC Sunspot Group 323 (NOAA Active Region 3906).
The greater than 2 MeV electron flux, as measured by the GOES-16 satellite, remained below the 1000 pfu alert threshold, and
it is expected to remain below the threshold during the next 24 hours. The 24h electron fluence was at normal levels and is expected to remain at these levels.
