The SIDC is part of the Royal Observatory of Belgium and a partner in the Solar Terrestrial Center of Excellence (STCE).


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.
