Solar activity has been very low with only a single notable C flare peaking at 19:51 UT at C1.6 level and originating from NOAA AR 2172. Background X-ray radiation has steadily increased to the C level. All 6 active regions on disc appear stable with NOAA AR 2172 the most significant potential flaring source. C flares should be expected with a chance for an M-flare especially from this region. The slightly enhanced proton levels (below the event threshold) observed yesterday have meanwhile settled to almost nominal values. An at least partial halo CME was recorded in SOHO/LASCO C2 data starting at around 7:36 UT. Analysis is ongoing regarding its source and potential impact, but first analysis seems to point to a source on the far side similar to the second CME observed yesterday. Solar wind speed has been stable, mainly within the 400-460 km/s range. Total magnetic field has slightly increased from between 5-6 nT to between 6-7 nT with Bz variable but now predominantly negative up to -6nT. Geomagnetic conditions were quiet to unsettled (both NOAA Kp and local K Dourbes 2-3). Later today we may see the arrival of a coronal hole high speed stream likely to last over the coming days. Associated enhanced geomagnetic activity (periods of active conditions) is possible.
