INFO FROM SIDC - RWC BELGIUM 2020 Dec 02 12:44UTC

Solar activity was relatively quiet, with only a single C flare peaking at
C1.4 magnitude at 23:20UT from NOAA region 2786.
There are 3 regions on disk of which 2 are classified as beta regions. The
largest is NOAA AR 2786, already on disk for a while, and there is the new
region NOAA AR 2790 that just rotated into view. Both appear relatively
inactive and stable.
Further C flares can be expected. An isolated M flare is possible but has a
low probability (10%).

As reported yesterday, the C1 flare peaking at 7:21UT December 1
originating from NOAA AR 2787 was associated with a dimming and EUV wave
and an associated CME visible in SoHO/LASCO from 7:12UT. While the core of
the CME is clearly not directed directly Earthward, a shock signature can
be seen expanding over the South and there are also faint signatures over
the North. Hence the CME could potentially be claimed to be classified as
partial Halo.
There is a chance for a glancing blow at Earth from this CME. If it occurs,
it is expected from the morning of December 4.
No other Earth directed CMEs have been observed in coronagraph data.

The greater than 10MeV proton flux seemed to decay but ultimately remained
enhanced reaching to 6pfu. It is not expected to rise much further although
that can not be excluded.
The greater than 2MeV electron flux did not exceed the 1000 pfu alert
threshold during its diurnal maximum. The 24h electron fluence was at
moderate levels and is expected to be at normal to moderate levels over the
next 24 hours. An increasing trend is expected following the recent Solar
wind enhancements.

Solar wind conditions remained enhanced with Solar wind speed above 500
km/s for most of the period. But after 7UT, solar wind speed came to lie in
the more nominal 400-450 km/s regime. The interplanetary magnetic field
magnitude was around a nominal 5nT with a variable and unremarkable
North-South orientation. The phi angle was mostly in the negative sector
(towards the Sun).
There were no signs of possible perturbations associated to the November 29
CME.
Essentially nominal Solar wind conditions are expected with a slight chance
for perturbations from the morning of December 4 onwards associated to the
December 1 CME.

Geomagnetic conditions were quiet (both local K Dourbes and NOAA Kp 0-2).
Geomagnetic conditions are expected to be quiet over the next 24 hours,
followed by possibly active conditions or minor geomagnetic storming should
a glancing blow from the December 1 CME occur.
