Solar activity was low. Several low level C class flares occurred, originating from NOAA regions 2277 and 2280 as well as from the SE limb. The largest events were two C2.6 flares from NOAA region 2270 peaking at 5:18UT and 5:58 UT respectively. NOAA 2277, 2280 and 2281 all showed some growth over the period. Flaring is expected to continue at C level. A filament eruption occurred at the SE limb just after 15:00UT. An associated CME was recorded in coronagraph data. It was directed eastward and will not be effecting Earth. Solar wind values became enhanced over the period. Solar wind speed increased from around 400 km/s to around 500 to 550 km/s. Total magnetic field also increased from around 7 nT to about 9 to 10 nT. Bz was variable with negative peaks down to -9.3 nT. The phi angle was positive. Geomagnetic conditions were quiet to unsettled (NOAA Kp 2-3, local K Dourbes 1-3). Slightly enhanced solar wind conditions are expected to persist. Geomagnetic conditions are expected to be quiet to unsettled with an isolated active period possible.
Today's estimated international sunspot number (ISN): 064, based on 13 stations.
