Zonnevlekkengebieden en zonnevlammen

The solar flaring activity was very low over the past 24 hours. The X-ray flux continued to decrease and is well below the C level. Few sunspots groups are visible on the disc. However they remain quiet with very few B-class flares. The solar flaring activity is expected to be at low levels over the next 24 hours, with possible C-class flares.

Coronale massa uitstoten

No Earth directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph imagery.

Coronale gaten

A negative polarity northern polar coronal hole that extends down to mid-latitudes has now fully crossed the central meridian and is currently on the geo-effective location. Another negative polarity equatorial coronal hole has crossed the central meridian on April 01.

Zonnewind

The solar wind conditions returned to slow speed regime, with solar wind speed ranging between 410 km/s and 480 km/s. The total interplanetary magnetic field was below 6.8 nT, and the Bz component was fluctuating between -5.4 nT and 6.0 nT. The solar wind conditions are expected to be slightly enhanced due to the high-speed stream from the negative polarity northern polar coronal hole (that crossed the central meridian on March 31), and due to the negative polarity equatorial coronal hole (that crossed the central meridian on April 01).

Geomagnetisme

Geomagnetic conditions were quiet to unsettled (NOAA Kp 1-3 and Local K Bel 2-3). Geomagnetic conditions are expected to be at unsettled with possible active conditions on April 03 and April 04 associated to a high-speed stream from coronal holes.

Proton flux niveaus

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

Elektronenfluxen in geostationaire baan

The greater than 2 MeV electron flux remained below the 1000 pfu threshold as measured by GOES 16. It is expected to remain below this threshold over the next days. The 24-hour electron fluence was at nominal levels. The electron fluence is expected to be at nominal levels over the next day.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 044, gebaseerd op 09 stations.
