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 01 12:26:51

Solar activity was dominated by C-class flares from NOAA AR 2290 and 2994.
The strongest was a C3.7 flare from NOAA AR 2290 peaking at 05:13 UT. More
C-class flares are expected with chances of M-class flaring.
Two full halo CMEs occurred on February 28. Both were backsided events. One
starting at 04:36 UT (LASCO-C2) and the other at 21:36 UT. Additionally a
CME directed to the NW was seen erupting at 15:12 UT, this is a frontside
event coming from north of NOAA AR 2292. This CME was slow, it  may arrive
to the Earth on March 4 and cause at most minor storm conditions.
Geomagnetic activity was dominated by a fast speed stream that caused
active conditions with isolated minor storm periods starting at midnight on
March 1 and still ongoing. The solar wind speed is around 500 km/s with
magnetic fields intensities of 10 nT. More active conditions can be
expected for today.
