Bulletin

Solar activity was at very low levels. The Sun is still spotless, but this may change as two small active regions at resp. latitudes S10 and N25 are about to rotate over the east limb as seen in SDO/AIA and STEREO-A/EUVI imagery. 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. Some small and patchy equatorial coronal holes (CHs) are present on the solar disk.

Solar activity is expected to remain at very low levels.

Solar wind conditions were at background levels. Solar wind speed varied steadily between 330 and 370 km/s (ACE). Bz undulated between -5 and +5 nT. The direction of the interplanetary magnetic field (phi angle) was variable. Geomagnetic conditions were at quiet levels, with an unsettled episode (09-12UT) recorded at Dourbes.

Geomagnetic activity is expected to remain mostly at quiet levels, with an isolated unsettled interval remaining possible.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 000, basierend auf 13 Stationen.
