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

INFO FROM SIDC - RWC BELGIUM 2019 Feb 15 12:30UTC

The solar activity has been quiet over the past 24 hours, with the X-ray
flux remaining below B-class level. The probability of C-class flares
occurring remains very low and quiet conditions are expected to continue
over the next 24 hours.

No Earth directed Coronal Mass Ejections (CMEs) have been detected. The
greater than 10MeV proton flux remained at background levels over the past
24 hours and is expected to remain so.

Over the last 24 hours the solar wind began to slowly decrease from 530 to
450 km/s. The total magnetic field strength fluctuated around 4.0 nT, while
the Bz component fluctuated between -3.0 and 3.5 nT. The slightly enhanced
solar wind conditions are expected to continue over the next 24 hours
before gradually decreasing as the Earth leaves the influence of the solar
wind stream associated with the extended southern polar coronal hole, which
first crossed the central meridian on the 10th of February.

The geomagnetic conditions were quiet to unsettled over the last 24 hours,
with the Kp (NOAA) and the local K (Dourbes) indices ranging between 0-3.
The geomagnetic conditions are expected to continue to be unsettled as the
enhanced solar wind associated with the extended southern polar coronal
hole continues to influence the Earth over the coming hours.
