Bulletin

Solar activity was at very low levels and is expected to remain so. The solar disk was spotless.

No earth-directed coronal mass ejections (CMEs) were observed in the available coronagraphic imagery.

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.

The solar wind speed ranged between 280 km/s and 330 km/s (DSCOVR and ACE). The phi angle was initially in the positive sector but switched into the negative sector between 00:30 and 10:15 on July 13. The total magnetic field fluctuated around 4nT for the first half of the period before increasing from 00:30, after the change of phi angle, and reached a maximum of 11 nT. Bz ranged between -9 and +5 nT.

Geomagnetic activity was mostly quiet with a localized unsettled to active period recorded by K-Dourbes (local K Dourbes and NOAA Kp recorded values between 0-4 and 0-2, respectively). Geomagnetic conditions are expected to be mostly quiet, with further unsettled intervals possible on 13 July from coronal hole wind stream effects, and on 14 July from a glancing blow from the 09 July CME. An isolated active interval is not excluded.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 27 stations.
