Bulletin

Solar activity was at very low levels. The visible solar disk has returned to spotlessness. 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 varied between mostly 450 and 520 km/s until about 04UT, when it gradually shifted into a less enhanced range between 400 and 450 km/s (ACE). Bz undulated between -4 and +4 nT. The interplanetary magnetic field (phi angle) was predominantly directed away from the Sun (positive sector). Both Kp and K Dourbes recorded quiet to unsettled geomagnetic conditions.

Geomagnetic activity is expected to remain at quiet to unsettled levels until around 4 October, when the wind stream from a patchy negative polarity coronal hole in the southern solar hemisphere may exert some influence on the earth environment. Mostly unsettled conditions are expected, with a chance on an isolated active interval.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 000, basierend auf 16 Stationen.
