Bulletin

NOAA 2381 simplified further and produced the only flare of the period, a C1.9 flare peaking at 03:37UT. The other regions are quiet. No obvious Earth-directed coronal mass ejections (CME) were observed.

Further C-class flaring is expected.

Solar wind speed varied between 350 and 400 km/s, with Bz fluctuating between -4 and +4 nT. Quiet to unsettled geomagnetic conditions were observed and are expected to persist.

Active geomagnetic conditions are possible starting late on 10 July, under the first effects of the equatorial coronal hole wind stream. A minor storming episode is not excluded.

Today's estimated international sunspot number (ISN): 111, based on 20 stations.
