Zonnevlekkengebieden en zonnevlammen

Solar flaring activity was moderate over the past 24 hours. NOAA AR 3489 was the source of the flare with the highest output in X-ray over the past 24 hours, the M1.1 flare, which peaked at 24 November 09:34 UT.

Coronale massa uitstoten

From the Coronal Mass Ejections (CMEs) observed the past 24 hours, none is currently believed to be earth-directed. Additionally, it is unclear where there was a disk-centre CME following the C4.1 flare peaking at 23 November 21:05UT, with source of origin NOAA AR 3490. Further analysis will be made as more data become available.

Coronale gaten

here is one coronal hole present centre-disk, the mid latitude positive polarity coronal hole.

Zonnewind

Solar wind parameters are in the slow solar wind regime, with some transient features having a mild influence. Over the next 24 hours, we are expecting the arrival of a high speed stream emanating from the mid latitudinal positive polarity coronal hole as well as impact from the only slightly anticipated glancing blow from the CME occurring at 22 November 06:48UT.

Geomagnetisme

Geomagnetic conditions were quiet to unsettled (local K Belgium 3) over the past 24 hours. Geomagnetic conditions are expected to be quiet to unsettled, with a slight probability of active conditions over the next 24 hours, due to possible high-speed stream arrival.

Proton flux niveaus

Over the past 24 hours the greater than 10 MeV GOES proton flux was below threshold and is expected to remain so over the next 24 hours.

Elektronenfluxen in geostationaire baan

The greater than 2 MeV electron flux was just below the 1000 pfu threshold, as measured by GOES 16. It is expected to increase towards moderate levels in the next 24 hours. The 24 hour electron fluence was at normal levels, it is expected too increase towards moderate levels for the next 24 hours.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 165, gebaseerd op 11 stations.
