INFO FROM SIDC - RWC BELGIUM 2015 Feb 06 12:28:38

Solar activity was low, with only a couple of isolated low level C flares. The strongest one originated from NOAA region 2280 (Catania 82) peaking at 10:17 UT at C1.4 level only.
A new spotted region started to appear near S10W45.
We expect some further C flaring, mainly from NOAA regions 2277 and 2280.
Incomplete SOHO LASCO coronagraph data so far seem to indicate that the filament eruptions of February 4 did not result in Earth directed CMEs. Solar wind conditions showed a sector boundary crossing with the magnetic field phi angle completing the shift which was started in the previous reporting period and settling on a firmly positive value during the present reporting period. Associated with this shift the total magnetic field increased from levels around 3.5 nT to values in the 6-8 nT range. Bz was variable with negative peaks down to -6.4 nT. Solar wind speed remained
in the 400 to 450 km/s range.  Geomagnetic conditions were quiet to active (both NOAA Kp and local K Dourbes 1-4), with the active period associated to the sector boundary  crossing.
Similar solar wind conditions are expected to persist, with associated  quiet to unsettled geomagnetic conditions.
