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 2021 Mar 02 12:30UTC

Apart from a small new Alpha region that is already decaying again, the Sun
is spotless, and it did not produce any C flares in the past 24 hours. The
chance for a C flare in the next 24 hours is estimated at only 1%.

No Earth-directed Coronal Mass Ejections (CMEs) were observed in available
coronagraphic imagery.

The greater than 10 MeV proton flux was at nominal levels in the past 24
hours, and is expected to stay at nominal levels in the next 24 hours. The
greater than 2 MeV electron flux was at nominal levels in the past 24
hours; moderate values are possible in the next 24 hours. The greater than
2 MeV electron fluence was at nominal levels during the past 24 hours, and
is expected to remain so in the next 24 hours.

Solar wind speed near Earth as registered by DSCOVR first decreased from
about 470 km/s to about 350 km/s and then increased again to about 590
km/s, possibly related to the expected arrival of a high speed stream
associated with the negative polarity southern crown coronal hole that
crossed the Central Meridian on February 26. The Interplanetary Magnetic
Field (IMF) was predominantly oriented towards the Sun and its magnitude
varied between about 1 and 12 nT, with current values around 8 nT. Bz was
not below -5 nT for extended periods. Enhanced solar wind conditions are
expected in the next 24 hours.

Quiet to active conditions (K Dourbes between 1 and 4; NOAA Kp between 2
and 3) were registered in the past 24 hours. Active geomagnetic levels (K
Dourbes = 4) are possible on March 2, 3 and 4, with a chance for minor
geomagnetic levels (K Dourbes = 5).
