Solar flaring activity over the last 24 hours has been at moderate levels, with one M-class flare. The strongest flare was an M1.5 flare peaking at 16:11 UTC on December 08, produced by SIDC Sunspot Group 305 (NOAA Active Region 3912, magnetic type beta). There are currently six numbered active regions on the solar disk. The most complex one is SIDC Sunspot Group 330 (NOAA Active Region 3916, magnetic type beta-gamma). SIDC Sunspot Group 302 (NOAA Active Region 3910) and SIDC Sunspot Group 331 (NOAA Active Region 3918) have rotated behind the west limb. SIDC Sunspot Group 329 (NOAA Active Region 3915) has decayed into plage. SIDC Sunspot Group 332 (NOAA Active Region 3920, magnetic type beta) has rotated on disk from the east limb. SIDC Sunspot Group 333 (NOAA Active Region 3919, magnetic type beta) has emerged in the southeast quadrant, east of SIDC Sunspot Group 330 (NOAA Active Region 3916), near the central meridian. The solar flaring activity is expected to be at moderate levels over the next 24 hours, with M-class flares expected and a small chance for X-class flares.
Preliminary analysis of the Coronal Mass Ejection (CME) observed in LASCO/C2 coronagraph imagery starting at 09:24 UTC on December 08 suggests no impact on Earth. No other Earth-directed CMEs were observed in the available coronagraph imagery.
A positive polarity coronal hole in the northern hemisphere, SIDC Coronal Hole 82, is still crossing the central meridian.
The greater than 10 MeV proton flux was below the threshold level over the past 24 hours. It is expected to remain below the threshold level over the next 24 hours, pending no further eruptive activity from SIDC Sunspot Group 305 (NOAA Active Region 3912).
The greater than 2 MeV electron flux measured by GOES 16 and GOES 18 was below the threshold level in the last 24 hours and it is expected to remain so over the next 24 hours. The 24-hour electron fluence is presently at normal levels and is expected to remain so over the next 24 hours.
