Solar activity was low. Several low level C flares were recorded from Catania group 92 (NOAA 2371). The largest was peaking at C3.2 level at 00:01UT. Catania group 92 (NOAA 2371) and 87 (NOAA 2367) are the most likely sources of flaring activity. Further C level flaring is expected with a slight chance for M class flares. No Earth directed CMEs were recorded. In the decaying phase of the high speed stream, solar wind speed and total magnetic field saw a slight increase around 18:00 UT. Total magnetic field picked up to around 9 nT and speed varied around 560 km/s for a while before resuming their decline. Bz was variable but pronounced negative since midnight, though remaining above -6.5 nT. Geomagnetic conditions continued to be quiet to unsettled (NOAA Kp 2-3) with an isolated local period of active conditions (K Dourbes 1-4). The high speed stream influence is expected to further decline with quiet to unsettled geomagnetic conditions as a consequence.
Today's estimated international sunspot number (ISN): 066, based on 15 stations.
