NOAA 2339 remains the dominant active region on the visible solar disk. Over the past 24 hours, it produced only low-level C-class flares with the emergence of some opposite polarity flux in its trailing portion. The other sunspot regions were quiet and produced at most a single low- level C-class flare. The strongest flare was a C2.5 flare peaking at 04:09UT (11 May) and was associated to a horseshoe shaped filament eruption located between active regions NOAA 2342 and 2343. Coronagraphic imagery is awaited to assess the presence and direction of any related coronal mass ejection (CME).

Further C-class flaring is expected, with a chance on an M-class flare. Unsettled to active geomagnetic conditions continued in response to the arrival of the 6 May CME. Solar wind speed declined to 350 km/s (18:00UT) and stayed at that level until about 07:00UT when it gradually started to climb to its current 380 km/s. Bz varied between -11 and +15 nT, with a sustained negative period at about -10nT between 19:00 and 02:00UT. The high speed stream of a negative coronal hole is expected to influence the geomagnetic field starting around 12 May.

Active to minor storming conditions are expected on 12 and 13 May.
