SIDC FORECAST 
SOLAR FLARES  : C-class flares expected, (probability >=50%)
GEOMAGNETISM  : Active conditions expected (A>=20 or K=4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 02 Jul 2025  10CM FLUX: 126 / AP: 024
PREDICTIONS FOR 03 Jul 2025  10CM FLUX: 124 / AP: 031
PREDICTIONS FOR 04 Jul 2025  10CM FLUX: 122 / AP: 024

Solar Active Regions and flaring: Solar flaring activity over the past 24
hours was low, with few C-class flares recorded. The largest flare was a
C1.1 flare, peaking at 11:29 UTC on July 02, associated with SIDC Sunspot
Group 513 (NOAA Active Region 4132; magnetic type alpha). There are
currently ten numbered active regions on the visible solar disk. SIDC
Sunspot Group 537 (NOAA Active Region 4126; beta) is expected to rotate
over the west limb in the coming hours. Solar flaring activity is expected
to be low over the next 24 hours, with C-class flares very likely and a
small chance for M-class flares.

Coronal mass ejections: No Earth-directed CMEs were observed in the
available coronagraphic imagery over the past 24 hours.

Solar wind: Over the past 24 hours, solar wind parameters (ACE and DSCOVR)
reflected a return to slow solar wind conditions. The solar wind speed
decreased from about 530 km/s to around 380 km/s. The interplanetary
magnetic field remained below 7 nT, and its southward component fluctuated
between -3 nT and 3 nT.  Solar wind conditions might become slightly
elevated over the next days due to the possible arrival of an ICME
associated with a partial halo CME (SIDC CME 523), observed lifting from
the Sun on June 28, and the anticipated high-speed stream arrival from the
recurrent negative polarity coronal hole (SIDC Coronal Hole 111).

Geomagnetism: Geomagnetic conditions were quiet globally and quiet to
unsettled locally, over Belgium (NOAA Kp: 1 to 2, K-Bel: 1 to 3).
Geomagnetic conditions are expected to remain at quiet to unsettled levels,
with a chance of increasing to active conditions and isolated minor or
moderate storm periods on July 02-03, due to the possible arrival of an
ICME associated with a partial halo CME (SIDC CME 523) observed lifting
from the Sun on June 28, and the expected high-speed stream arrival from
the recurrent negative polarity coronal hole (SIDC Coronal Hole 111).

Proton flux levels: The greater than 10 MeV GOES proton flux was below the
threshold level over the past 24 hours and is expected to remain so for 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 threshold over the past 24
hours. The greater than 2 MeV electron flux may exceed this threshold again
in the coming days. The 24-hour electron fluence was at moderate levels and
is expected to remain at moderate levels over the next 24 hours.
