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


During last 24 hours only one C-class flare was reported. The C1.5 flare
that peaked at 03:49 UT this morning, originated from the NOAA AR 2770. No
obvious on-disc signatures of the possibly associated CME were observed.
More will be reported when coronagraph data become available.
NOAA AR 2770 has still beta configuration of its photospheric magnetic
field, and might be the source of B-class or isolated C-class flares in the
coming hours. 
During last 24 hours there were no Earth directed CMEs and the solar
protons remained at the background level.

The solar wind speed is presently about 420 km/s, and the interplanetary
magnetic field magnitude is 4 nT. The geomagnetic conditions are quiet, and
we expect them to stay so in the coming hours.
