Solar Active Regions and flaring: Solar flaring activity over the past 24
hours was low, with several C-class flares recorded. The largest flare was
a C1.9 flare, peaking at 18:34 UTC on June 30, associated with SIDC Sunspot
Group 543 (NOAA Active Region 4130; magnetic type beta). There are
currently thirteen numbered active regions on the visible solar disk. SIDC
Sunspot Group 541 (NOAA Active Region 4129) is currently the most
magnetically complex region, with a beta-gamma configuration, but produced
only low-level C-class flaring. SIDC Sunspot Group 543 (NOAA Active Region
4130) and SIDC Sunspot Group 513 have rotated onto the disk from the
southeast limb. SIDC Sunspot Group 527 (NOAA Active Region 4118) is
expected to rotate over the west limb in the coming hours. Two new active
regions emerged in the southwest and northwest quadrants during the period,
numbered SIDC Sunspot Groups 544(beta) and 545(beta), respectively, but did
not produce any significant flaring activity. Low-level flaring activity
was also produced by SIDC Sunspot Group 537 (NOAA Active Region 4126;
beta). The remaining active regions are relatively simple (magnetic type
alpha or beta) and did not produce any significant flaring activity. Solar
flaring activity is expected to be low over the next 24 hours, with C-class
flares very likely and a 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 the waning influence of high-speed streams (HSSs) from SIDC
Coronal Hole 116 (negative polarity). The solar wind speed ranged between
450 km/s and 550 km/s. The interplanetary magnetic field remained below 6
nT, and its southward component fluctuated between -6 nT and 6 nT. Slow
solar wind conditions are expected to prevail over the next days, with a
chance of a weak enhancement from July 02 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 at quiet to unsettled levels
globally (NOAA Kp: 2 to 3). Locally, over Belgium, active conditions were
reached between 18:00 and 21:00 UTC on June 30 (K-Bel: 4). 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 from July 02, 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 is expected to exceed this
threshold again in the coming days. The 24-hour electron fluence was at
moderate to high levels and is expected to remain at these levels over the
next 24 hours.
