Bulletin

Solar activity was at very low levels and is expected to remain so. Small sunspot region NOAA 2766 is quiet and located near disk centre.

The greater than 10 MeV proton flux and the greater than 2 MeV electron flux were at nominal levels during the last 24 hours and are expected to remain so.

No earth-directed coronal mass ejections (CMEs) were observed in available coronagraphic imagery. The bulk of yesterday's CME (5 July) seems not to be earth directed and a glancing blow is unlikely.

The earth environment remained under the influence of an enhanced wind stream associated with an extension of the positive polarity northern polar coronal hole (CH). Solar wind speed varied between 500 and 430 km/s, ending the period near 490 km/s (DSCOVR). Bz varied between -6 and +5 nT. The direction of the interplanetary magnetic field (phi angle) was predominantly directed away from the Sun (positive sector).

Geomagnetic activity was at quiet to unsettled levels. Geomagnetic conditions are expected to be quiet, with a chance on an isolated unsettled interval during the ongoing period.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 006, basierend auf 27 Stationen.
