Bulletin

Solar flaring activity was at very low levels. No significant flares have been recorded. A small and as yet unnumbered sunspot region rotated onto the disk near N30E60. Solar 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 2MeV electron flux was at moderate levels between 12:30UT and 19:00UT. It is expected to become further enhanced over the next 24 hours. The solar wind speed near Earth increased from 420 to 530 km/s at 15:00UT and then continued to oscillate around 500 km/s (DSCOVR), as a result of the solar wind associated with the Coronal Hole which began to cross the Central Meridian on Mar 26. The Interplanetary Magnetic Field (IMF) was predominantly oriented towards the Sun (phi angle in the negative sector) with the magnitude varying between 2 and 8 nT. Bz ranged between -7 and +6 nT.

Active to minor storm (K Dourbes = 5) geomagnetic conditions were registered for the past 24 hours (K Dourbes recorded values 1-5 and NOAA Kp 1-4). Active (K Dourbes = 4) geomagnetic conditions are expected for the next 24 hours, while Earth continues to be under the influence of the fast solar wind.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 013, basierend auf 22 Stationen.
