Bulletin

Solar activity was at very low levels. The small region which emerged yesterday (Catania group 1, NOAA Active Region 2924) was stable. A new active region has just rotated onto the solar disk (Catania group 2, S33E78), but its complexity cannot yet be determined. Solar activity is expected to be at very low levels.

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

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours and is expected to remain so in the next 24 hours. The greater than 2MeV electron flux remained under the 1000 pfu threshold and is expected to remain just below this threshold in the next days. The 24h electron fluence was at normal levels and is expected to be at normal levels over the next 24 hours.

The Solar wind parameters reflected a slow solar wind regime. The solar wind speed ranged between 340 and 430 km/s. The total magnetic field magnitude oscillated around 5 nT, with a variable Bz component. The interplanetary magnetic field phi angle was predominantly in the positive sector (directed away from the Sun). The solar wind speed is expected to continue to reflect a slow solar wind regime over the next 48 hours.

Geomagnetic conditions were quiet (NOAA Kp 0-2 and local K Belgium 0-1) and are expected to be quiet over the next 48 hours.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 025, basierend auf 11 Stationen.
