INFO FROM SIDC - RWC BELGIUM 2019 Mar 18 12:30UTC

There are no active regions visible on the solar disk. No C-class flares in
past 24 h. Solar activity is expected to remain at very low levels.
 
No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar
protons have remained at background levels over the past 24 hours.

The solar wind speed is at 350 km/s with interplanetary magnetic fields of
5 nT. Geomagnetic conditions have been quiet to unsettled (K = 1 - 3) in
the past 24 h. A relatively long magnetic field with low variability
together with low temperature could have marked the arrival yesterday of
the March 12 CME. The effect of a high speed stream from a small equatorial
coronal hole, with positive magnetic field polarity, may reach the Earth in
about 24 h and cause up to active geomagnetic storm conditions (K = 4).
