Zonnevlekkengebieden en zonnevlammen

Solar flaring activity was low over the past 24 hours, with four C1 flares identified. SIDC Sunspot Group (SG) 831 (NOAA Active Region [AR] 4402, Beta magnetic configuration) produced two of those flares, while SIDC SG 828 (NOAA AR 4398, Beta magnetic configuration) and SIDC SG 826 (NOAA AR 4400, Beta-Gamma-Delta magnetic configuration) produced the rest. More C-class flaring activity is expected in the next 24 hours.

Coronale massa uitstoten

No Earth-directed Coronal Mass Ejections (CME) were observed in the last 24 hours.

Zonnewind

The Solar Wind (SW) conditions remain affected by a High Speed Stream (HSS) during the past 24 hours. However, the effect is waning as the SW speed gradually felt from 730 to as low as 570 km/s. The interplanetary magnetic field (B) ranged from 2 nT to 6 nT, and its North-South component (Bz) varied from -6 nT to 4 nT. For the next 24 hours the HSS effect is expected to cease and the SW gradually return to a slow SW regime.

Geomagnetisme

During the past 24 hours the global geomagnetic conditions first reached minor storm levels (NOAA Kp 5 at 15:00 - 18:00 UTC and 5- at 12:00 - 15:00 UTC) and then decreased to unsettled to active levels. The local conditions followed a similar pattern during the same period of time with K BEL 5 at 15:00 - 21:00 UTC and quiet to active levels for the rest of the past 24 hours. Further decrease of the K indices is expected in the next 24 hours, as active to quiet conditions are expected to prevail.

Proton flux niveaus

The greater than 10 MeV proton flux, as measured by the GOES-19 satellite, was at background levels over the past 24 hours and is likely to remain so in the next 24 hours.

Elektronenfluxen in geostationaire baan

During the past 24 hours, the greater than 2 MeV electron flux as measured by GOES 19 was above the 1000 pfu alert threshold, with a peak value of 7000 pfu. For the rest of the past 24 hours a further increase is expected. During the past 24-hours the electron fluence increased but remained at moderate levels. In the next 24 hours it is expected to increase further and probably reach high levels.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 113, gebaseerd op 18 stations.
