NOAA 2339 is decaying and produced only low-level C-class flares. NOAA 2342 produced the strongest flare of the period, a C3.5 flare peaking at 05:59UT and located in its trailing portion. The flare was associated with a series Type III radio-burst, and a surge was observed in H-alpha. The greater than 10 MeV proton flux is nearly back at nominal levels. No earth-directed coronal mass ejections (CME) were observed over the period.

Further C-class flaring is expected, with a chance on an M-class flare.

Moderate geomagnetic storming has been observed as the Earth is under the influence of the high speed stream (HSS) of a recurrent coronal hole. Kp reached 6 between 03:00 and 09:00UT, while Dourbes reported a maximum K of 4. Solar wind speed is currently at about 700 km/s, while Bz-values were at -14 nT between 04:00 and 04:30UT.

Further episodes of minor to moderate geomagnetic storming are expected.
