There are currently 9 sunspot regions on the visible disk. Most are stable, with only NOAA 2034, 2035 and 2036 having a more complex beta- gamma structure. These three groups produced 7 of the 9 low-level C-class flares that were observed during the last 24 hours. Dynamic but small active regions NOAA 2038 and 2045 produced the two other C flares. Several CMEs were observed near and behind the northwest limb, related to continuing activity near NOAA 2032/2033. None of these CMEs had an earth- directed component. Further C-class flaring is expected, with a small chance on an isolated M-flare. Active to minor storm conditions were observed in response to the ICME related to the M7 flare. Solar wind speed gradually declined from 700 to 600km/s, with Bz varying mostly between +11 and -7nT. Geomagnetic conditions are expected to be quiet with an occasional active period as the geomagnetic field recovers from the ICME impact.
