SIDC FORECAST 
SOLAR FLARES  : M-class flares expected (probability >=50%)
GEOMAGNETISM  : Quiet (A<20 and K<4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 15 Jan 2026  10CM FLUX: 125 / AP: 008
PREDICTIONS FOR 16 Jan 2026  10CM FLUX: 130 / AP: 012
PREDICTIONS FOR 17 Jan 2026  10CM FLUX: 130 / AP: 007

Solar Active Regions and flaring: Solar flaring activity was moderate over
the past 24 hours, with 1 M-class flare identified. The largest flare was a
M1.6 flare (SIDC Flare 6647) peaking on January 14 at 20:33 UTC, which was
produced by SIDC Sunspot Group 740 (NOAA Active Regions 4321, 4341). A
total of 5 numbered sunspot groups currently identified on the disk. SIDC
Sunspot Group 740 (NOAA Active Region 4341) and SIDC Sunspot Group 760
(NOAA Active Region 4340) have currently Beta-Gamma magnetic configuration.
SIDC Sunspot Group 763 (NOAA Active Region 4343) currently located at
S10E15 has a Beta magnetic configuration and was growing over the past 24
hours. Solar flaring activity is expected to be moderate over the next 24
hours, with M-class flares very likely and a small chance for X-class
flares.

Coronal mass ejections: No new Earth-directed Coronal Mass Ejections (CMEs)
have been detected in the available coronagraph images.

Solar wind: Solar wind conditions have transited to fast solar wind
conditions over the past 24 hours. The solar wind velocity gradually
reaches 640 km/s, potentially linked to HSS from SIDC CH 137. The
interplanetary magnetic field was around 5 nT, with the Bz reaching a
minimum value of -6 nT.  Solar wind conditions are expected to remain
enhanced over the next 24 hours.

Geomagnetism: Geomagnetic conditions were quiet to unsettled globally and
locally (Kp 3-, K bel 3) over the past 24 hours. Quiet to unsettled
geomagnetic conditions are expected over the next day.


Proton flux levels: The greater than 10 MeV proton flux remained below the
10 pfu threshold and is expected to remain so over the next days.


Electron fluxes at GEO: The greater than 2 MeV electron flux was above the
1000 pfu threshold for the past 24 hours and is expected to remain so in
the upcoming day. The 24h electron fluence was at moderate level and is
expected to remain so in the next day.
