Welcome to the Solar Influences Data Analysis Center (SIDC), which is the solar physics research department of the Royal Observatory of Belgium. The SIDC includes the World Data Center for the sunspot index and the ISES Regional Warning Center Brussels for space weather forecasting.

The solar flaring activity is currently on the low C-level. The strongest
flare of the past 24 hours is the C1.6 flare peaking at 05:29 UT today in
the NOAA AR 2492. NOAA AR 2495 exhibited strong emergence of the
photospheric magnetic flux and may become more flare-productive, as well as
NOAA AR 2494 that developed beta-delta configuration of its photospheric
magnetic field. We expect flaring activity on the C-level in the coming
hours, with an isolated M-class flare possible but unlikely. 
The Earth is currently inside a slow (around 450 km/s) solar wind flow with
slightly elevated (5-8 nT) interplanetary magnetic field (IMF) magnitude.
The north-south IMF component Bz was consistently negative in the second
half of yesterday and early today, so NOAA reported Kp = 5 and Dourbes
reported K = 4 this morning. The IMF direction became more irregular since
that time, so we expect quiet geomagnetic conditions in the coming hours.
Tomorrow we expect the arrival of an ICME associated with the partial halo
CME detected on the Sun on February 5, possibly resulting in active to
minor storm geomagnetic conditions.
