INFO FROM SIDC - RWC BELGIUM 2019 Aug 22 12:30UTC

The solar activity has been quiet over the past 24 hours. The sun is
currently spotless and the X-ray flux remained below B-level. Solar
activity is expected to remain at low levels for the next 24 hours.

No Earth-directed coronal mass ejections (CME) were observed over the last
24 hours in the available coronagraph imagery. The greater than 10 MeV
proton flux remained at background levels over the past 24 hours and is
expected to remain at low levels. 

The Earth is currently under the slow solar wind regime: The wind speed
remained about 350 km/s, the total interplanetary magnetic field was below
5 nT, and the Bz component showed small fluctuations around 0 nT (as
recorded by ACE). The solar wind parameters are expected to remain close to
the nominal levers.

Quiet geomagnetic conditions were observed and are expected to remain for
the next period.
