INFO FROM SIDC - RWC BELGIUM 2021 Nov 29 12:37UTC

Solar activity was at very low levels over the past 24 hours. There are
three Active Regions (AR) visible on the Sun. NOAA AR 2899 has now rotated
over the west limb, while a new simple region (NOAA AR 2901, alpha magnetic
field configuration) has emerged in the North East quadrant. NOAA AR 2898
and 2900 are the largest regions on disk, both with beta magnetic field
configuration. There is estimated to be a 50 percent probability of C-class
flares in the next 24 hours.

There was a filament eruption observed in the southern hemisphere, visible
from 06UT Nov 29. The bulk of the eruption appears to be directed to the
south of the Sun-Earth line but a full analysis will be made when
coronagraph data become available. No Earth directed Coronal Mass Ejections
(CMEs) have been detected in the available coronagraph imagery.

The greater than 10 MeV proton flux was at nominal levels in the past 24
hours and is expected to remain at nominal levels in the next 24 hours. The
greater than 2 MeV electron flux was below the 1000 pfu alert threshold in
the past 24 hours and is expected to remain so in the next 24 hours. The
greater than 2 MeV electron fluence was at nominal levels in the past 24
hours, and is expected to stay at nominal levels in the next 24 hours.

The magnetic field was enhanced at the start of the period, due to the
ongoing passage of the ICME that arrived on Nov 27.  The magnetic field
gradually decreased from 12 to 5 nT over the past 24 hours. Bz varied
between -7 and 9 nT, with an extended period of negative Bz between 16UT
Nov 28 and 05UT Nov 29. The solar wind speed remained low, oscillating
around 390 km/s. 

Geomagnetic conditions were at quiet to active levels (NOAA Kp and K-BEL
recorded values of 1-4). Geomagnetic conditions are expected to be quiet to
unsettled on Nov 29 and Nov 30.
