Bulletin

The solar flaring activity over the past 24 hours was at low levels. The largest flare was a C1.3-class flare peaking at 17:02 UTC on Nov 08 and produced by the current most complex bipolar sunspot region on the solar surface visible from Earth (Catania Sunspot group 89, NOAA AR 3141). The other sunspot groups on the solar surface visible from Earth didn’t show any flaring activity. The flaring activity over the next 24 hours is expected to remain at low levels.

No Earth-directed coronal mass ejections were detected in the available coronagraph imagery over the past 24 hours.

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 2 MeV electron flux was below the 1000 pfu threshold over the past 24 hours and is expected to remain below the 1000 pfu threshold over the next 24 hours. The electron fluence was at normal to moderate levels and is expected to remain at normal levels over the next 24 hours.

Over the past 24 hours, the solar wind parameters (ACE and DSCOVR) were close to nominal levels reflecting a slow solar wind speed regime: The solar wind speed was between 315 km/s and 400 km/s; the total interplanetary magnetic field decreased to values around 5 nT; and the southward interplanetary magnetic, Bz component ranged between -7.7 nT and 2.7 nT. The high-speed streams from a small and narrow equatorial coronal hole may arrive today and enhanced the solar wind conditions near Earth.

The geomagnetic conditions over the past 24 hours were quiet to unsettle (K-Belgium, Kp-NOAA ranged between 1 and 3). Quiet to unsettled geomagnetic conditions with possible short periods of active geomagnetic conditions are possible due to the arrival of the high-speed streams from a small and narrow equatorial coronal hole.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 089, basierend auf 16 Stationen.
