SIDC FORECAST 
SOLAR FLARES  : C-class flares expected, (probability >=50%)
GEOMAGNETISM  : Minor storm expected (A>=30 or K=5)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 06 Nov 2026  10CM FLUX: 128 / AP: 017
PREDICTIONS FOR 07 Nov 2026  10CM FLUX: 132 / AP: 043
PREDICTIONS FOR 08 Nov 2026  10CM FLUX: 134 / AP: 028

Solar Active Regions and flaring: Solar flaring activity reached moderate
levels over the past 24 hours, with one M-class flare and multiple C-class
flares recorded. The largest flare was an M3.5 flare (SIDC Flare 8823),
peaking at 18:33 UTC on November 5, associated with SIDC Sunspot Group 992
(NOAA Active Region 4566; magnetic type beta-gamma-delta). A type II radio
burst was detected, starting from 18:28 UTC on November 05, likely
associated with M3.5 flare. There are currently seven numbered sunspot
groups on the visible solar disk. SIDC Sunspot Group 992 is the largest and
most magnetically complex sunspot group on the visible solar disk and was
the main driver of the observed flaring activity, together with SIDC 980
(NOAA Active Region 4570; magnetic type alpha), which is currently rotating
onto the visible solar disk over the east limb. Solar flaring activity is
expected to be low over the next 24 hours, with C-class flares very likely
and a chance of M-class flares.

Coronal mass ejections: A narrow coronal mass ejection (SIDC CME 742) was
first observed at 19:12 UTC on November 5 in LASCO/C2 coronagraph imagery.
The CME was directed predominantly eastward, as viewed from Earth, and was
associated with the M3.5 flare (SIDC Flare 8823). The CME is not expected
to impact Earth. No Earth-directed CMEs were identified in the available
coronagraph imagery over the past 24 hours.

Solar wind: Over the past 24 hours, solar wind parameters (SOLAR-1 and ACE)
reflected slow solar wind conditions. The solar wind speed ranged between
310 and 350 km/s. The interplanetary magnetic field remained below 9 nT.
The north-south component of the interplanetary magnetic field, Bz, varied
between approximately -8 nT and 7 nT, with several intervals of southward
Bz. Solar wind conditions are expected to become slightly disturbed over
the next 24 hours due to the possible arrival of a high-speed stream
associated with the negative-polarity SIDC Coronal Hole 149.

Geomagnetism: Geomagnetic conditions were quiet to unsettled both globally
(NOAA Kp = 1 to 3) and locally over Belgium (K-Bel = 1 to 3) over the past
24 hours. Mostly unsettled to active geomagnetic conditions are expected
over the next 24 hours, with a chance of isolated periods of minor to
moderate geomagnetic storm conditions due to the expected arrival of a
high-speed stream associated with the negative-polarity SIDC Coronal Hole
149.

Proton flux levels: The greater than 10 MeV proton flux, as measured by
GOES-18, was at nominal levels over the past 24 hours and is expected to
remain so over the next 24 hours.

Electron fluxes at GEO: The greater than 2 MeV electron flux, as measured
by GOES-18 and GOES-19, exceeded the 1000 pfu alert threshold over the past
24 hours. The greater than 2 MeV electron flux is expected to remain mostly
below the 1000 pfu threshold over the next 24 hours. The 24-hour electron
fluence was at moderate levels and it is expected remain at normal to
moderate levels over the next 24 hours.
