Zonnevlekkengebieden en zonnevlammen

Solar flaring activity was low over the past 24 hours, with only C-class flares identified. The largest flare was a C3.8 flare (SIDC Flare 8165) peaking on July 06 at 18:40 UTC, which is possibly produced by SIDC Sunspot Groups 860 (NOAA Active Region 4479) behind the limb. A total of 5 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Group 910 (NOAA Active Region 4482) is the most complex group with its beta-gamma magnetic configuration, but it has produced only C-class flares in the past 24 hours. Solar flaring activity is expected to be low to moderate over the next 24 hours, with C-class flares expected and M-class flares likely.

Coronale massa uitstoten

No Earth-directed coronal mass ejections (CMEs) were detected in the available coronagraph observations during the last 24 hour.

Zonnewind

Earth was predominantly within the slow solar wind regime, except for a brief interval around 18:00 UTC on Jul 6, during which solar wind conditions were slightly enhanced. The solar wind speed ranged between 375 km/s and 540 km/s. The interplanetary magnetic field ranged between 5 nT and 7 nT. The North-South component (Bz) ranged between -5 and 6 nT. Slow solar wind conditions are expected to continue over the next 24 hours.

Geomagnetisme

Geomagnetic conditions were globally at quiet (NOAA Kp 1 to 2) and locally at quiet to unsettled conditions (K BEL 1 to 3). Quiet to unsettled conditions are expected in the next 24 hours.

Proton flux niveaus

The greater than 10 MeV GOES proton flux was below the threshold level over the past 24 hours and it is expected to remain so for the next 24 hours. A slight chance for a proton event if any major eruption occurs from SIDC Sunspot Group 886 (NOAA Active Regions 4478), which is on W limb.

Elektronenfluxen in geostationaire baan

The greater than 2 MeV electron flux, as measured by GOES-18 and GOES-19 satellites, remained above the 1000 pfu threshold level during the past 24 hours and is expected to remain so. It was possibly due to the enhanced solar wind speed on previous days. The 24h electron fluence was at moderate levels during the past 24 hours and is expected to remain so.
