Only B-class flaring was observed, the strongest a B9.2 flare peaking at 19:22UT and produced by NOAA 2591. NOAA 2585, 2588 and 2589 are gradually decaying. No earth-directed coronal mass ejections (CME) have been observed.
A C-class flare is possible, with a small chance on an isolated M-class event.
Solar wind parameters were at nominal values, with wind speed declining slightly from about 390 km/s to 360 km/s. Bz fluctuated between -3 and +3 nT. The interplanetary magnetic field (IMF) was mostly directed away from the Sun (positive). Geomagnetic activity was at quiet levels, with Dourbes reporting an unsettled episode during the 21-24UT interval.
Quiet to unsettled geomagnetic conditions are expected, with a chance on active intervals should the moderate speed stream from a polar coronal hole extension arrive at the earth environment later today.
Today's estimated international sunspot number (ISN): 067, based on 14 stations.
