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 2016 Feb 06 12:30UTC

Solar activity was low during the past reporting period, with only two C1
flares. Flaring activity originated from NOAA active regions (AR) 2494,
2496 and 2491. NOAA AR 2494 lost its delta component, but still has the
potential to produce multiple C-class flares. All other regions were mainly
unchanged and simple. 

A partial halo CME was observed with first measurements in SOHO-LASCO/C2
around 19h36 UT on February 5. The CME was rather faint, but with an
estimated angular width of about 120 degrees. The CME is propagating in the
Southwest direction with an estimated projected speed of 450 km/s. The CME
is associated with the eruption of a small filament near S20W20 (SDO/AIA
304 and GONG images) and seems to have an Earth directed component. An
Earth-directed component may arrive at February 9 around 7h UT.
Before the above mentioned eruption, two other small filaments disappeared
as well (starting around 3h UT near S00W40 and one around 18h25 UT near
S00E05). These eruptions did only result in insignificant coronagraphic
signatures.
More flares at the C-level are expected. 

The magnitude of interplanetary magnetic field (IMF) returned to normal
values around 5 nT. Solar wind speed is gradually decreasing with current
values near 450 km/s. 

Geomagnetic conditions were quiet (K=1-2) to unsettled (K=3), both at the
local (Dourbes) and global level (NOAA estimate), with one single time slot
of active (K=4) levels at Dourbes. Quiet to unsettled conditions are
expected.
