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 for the next 24 hours.

The solar wind speed steadily increased over the past 24 hours from 280 km/s to 395 km/s (DSCOVR). The total magnetic field also showed a generally increasing trend and reached a maximum of 9.6 nT. Bz was predominantly negative, with an extended southward deflection from 21:00 UT on 13 July with a minimum value of -9 nT. The phi angle alternated between the positive and negative sectors.

Geomagnetic activity was quiet at the start of the period and then became active due to the extended period of moderately strong negative Bz (local K Dourbes and NOAA Kp recorded values between 1-4). Geomagnetic conditions are expected to be unsettled with possible further active intervals on 14 July in response to any prolonged periods of negative Bz. Geomagnetic activity is expected to return to quiet levels from 15 July.
