Bulletin

Solar activity was at very low levels. A small and as yet unnumbered sunspot region developed near S09E75, producing a B1 flare at 01:45UT (GOES) and ending a 27 days stretch of spotless days (SILSO). No earth-directed coronal mass ejections (CMEs) have been observed in available coronagraphic imagery. The greater than 10 MeV proton flux was at nominal values.

Solar activity is expected to remain at very low levels.

Solar wind speed undulated between mostly 400 and 510 km/s, ending the period with values near 480 km/s (ACE). Bz ranged from -6 to + 5 nT, with negative stretches during the 12-15UT and 00-06UT intervals. Quiet to active geomagnetic conditions were recorded in both Kp and K Dourbes. The interplanetary magnetic field (phi angle) was mostly directed away from the Sun (positive sector).

Geomagnetic activity is expected to be at quiet to unsettled levels, with a decreasing chance on another active episode.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 011, gebaseerd op 14 stations.
