Bulletin

Solar X-ray flux remained below B level. Active Region (AR) 2760 (Mcintosh class: Bxo; Mag. type: Beta) has been quiet. Another small bipolar region, as yet unnumbered, located around S18W05 has emerged. Solar flaring activity is expected to remain at very low levels.

No Earth directed Coronal Mass Ejections (CMEs) were observed in the available coronagraphic imagery.

The greater than 10 MeV proton flux was at nominal levels over the past 24 hours and is expected to stay at nominal levels for the next 24 hours. The greater than 2 MeV electron flux was between nominal and moderate levels over the past 24 hours and is expected to be at nominal levels over the next 24 hours.

The solar wind speed near Earth oscillated around 400 km/s and the total magnetic field fluctuated around 5 nT (DSCOVR) over the past 24 hours. The Interplanetary Magnetic Field (IMF) was predominantly oriented towards the Sun (phi angle in the negative sector). Bz ranged between -6 and +3 nT. Nominal solar wind conditions are expected for Apr 27-29.

Geomagnetic conditions were quiet to unsettled (local K Dourbes and NOAA Kp recorded values between 0-3 and 1-3, respectively). Quiet geomagnetic conditions are expected for Apr 27-29 with isolated unsettled episodes possible.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 030, gebaseerd op 22 stations.
