NOAA 2385 (Catania 11) produced the only flare of the period: a C1 flare peaking at 16:13UT. The other sunspot regions were quiet. No obvious Earth-directed coronal mass ejections (CME) were observed. A 90 degrees wide CME first observed by LASCO/C2 at 16:24UT was the result of longlasting filamentary activity at and beyond the northwest solar limb. The bulk of the ejected material was directed well north of the ecliptic and away from Earth.
There remains a chance on an isolated C-class flare.
Initially, solar wind speed was stable around 350 km/s. A gradual increase started around 20:00UT, under the influence of the co-rotating interaction region (CIR). Current solar wind speeds seem slightly in decline from the maximum values near 640 km/s around 10:00UT. A sharp drop in particle density was observed shortly before 23:00UT, from an average of about 50-60 per cm3 to 4-7 per cm3. The direction of the interplanetary magnetic field turned away from the Sun between 22:00-23:00UT. Both are consistent with the proper arrival of the high speed stream (HSS) from the equatorial coronal hole. Bz fluctuated between -14 and +14 nT, but has been varying between much smaller values since 07:00UT (mostly between -6 and +6 nT).
As expected, active geomagnetic conditions were observed in Dourbes under the effects of the CIR and HSS. Globally, the NOAA Kp reached minor storming conditions during the 21:00-24:00 and 03:00-06:00 periods. Quiet to active geomagnetic conditions are expected to persist, with a minor storming episode not excluded.
Today's estimated international sunspot number (ISN): 096, based on 18 stations.
