Six low-level C-class flares were recorded during the period. The strongest was a C2.7 flare peaking at 10:48UT, apparently from a location near spotless region NOAA 2429. NOAA 2434 was the source of the 5 other C-class flares, its leading portion showing some magnetic polarity mixing, while its trailing portion contains only a few small sunspots. The two other sunspot groups currently visible on the solar disk were quiet. No earth-directed coronal mass ejections (CMEs) have been observed.

C-class flares are expected, with a chance on an isolated M-class flare from NOAA 2434.

Earth was under the influence of the high speed wind stream (HSS) from the wide northern coronal hole (CH). Solar wind speed was mostly declining from an initial 550 km/s to its current 450 km/S. Bz oscillated between -6 and +4 nT, with persistent values near -6 nT for 7 hours starting around 04:00UT. The latter period coincided with an increasing solar wind density and decreasing temperature, as well as an erratic behaviour of the direction of the interplanetary magnetic field (IMF), which up to that time was mostly pointing away from the Sun (positive). Quiet to locally active geomagnetic conditions were observed.

Mostly unsettled to active geomagnetic conditions are expected, with a chance on minor geomagnetic storming episodes as Earth is likely to pass through the HSS from the eastmost extension of the northern CH.
