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.

INFO FROM SIDC - RWC BELGIUM 2015 Mar 02 12:22:38

NOAA 2290, which is now near the NW solar limb, was responsible for most of
the C-class flaring over the last 24 hours. It was also the source of 2 M1
flares (peaking resp. at 06:39 and 09:48UT). Proton flux levels stayed
nominal. An actively flaring region is rounding the SE limb and produced
two low-level C-class flares. NOAA 2292 has some mixed magnetic polarities
but has remained quiet.
A 300 degrees wide partial halo CME was detected by Cactus in LASCO/C2
imagery on 01 March 2015 at 12:36UT.  With no obvious related signature on
the Sun's earth facing side, this halo CME seems to have been a backside
event. Several other CMEs have been recorded during the period, with the
most prominent CMEs related to flaring activity from NOAA 2290. None of the
observed CMEs has an Earth directed component.

There's a good chance on continued M-class flaring from NOAA 2290 as it
rotates further over the NW limb.

Active (K=4 at Dourbes) to minor geomagnetic storming (Kp=5) conditions
were recorded over the period as the Earth remained under the influence of
the high speed stream from the southern polar CH. Solar wind speed reached
maximum values near 700 km/s. IMF was directed towards the Sun, with Bz
mostly negative and oscillating between -10 and +11 nT.

The geomagnetic field is expected to range from unsettled to active
conditions, with a chance on a minor storming episode.
