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 05 12:21:40

The strongest event of the period was a C3.5 flare peaking at 09:47UT by
the active region at or just behind the southeast limb. Two C1 flares were
observed, with sources resp. NOAA 2293 and a spotless region currently
located at S10E40. Both eruptions showed interaction with a nearby
filament. If the filament near NOAA 2293 erupts, it may be geo-effective.
No earth-directed coronal mass ejections were observed.

C-class flaring is expected, with a chance on an M-class flare.

Quiet to unsettled geomagnetic conditions were observed, with locally
(Dourbes) an active episode at the beginning of the period. Solar wind
speed varied mostly between 530 and its current 440 km/s, with Bz mostly
positive and varying between -5 and +6 nT. The interplanetary magnetic
field was mostly directed away from the Sun.

Quiet to unsettled geomagnetic conditions are expected, until the arrival
of the high speed stream from a coronal hole late on 06 or on 07 March when
active episodes may be possible.
