NOAA 2603 produced a few small B-class flares including a B3.1 at 07:17UT, the strongest event of the period. The region will rotate over the west limb during the next 24 hours. Two other sunspot regions, Catania 50 (near disk centre) and an unnumbered region near N10W50 are small and quiet. No earth-directed coronal mass ejections (CMEs) were observed.
Quiet flaring conditions are expected to continue, with a chance on an isolated C-class flare.
Earth remained under the influence of the high speed stream (HSS) from the huge coronal hole (CH). Solar wind speed initially decreased further to values near 550 km/s by about 06UT before increasing again to its current values between 650 and 700 km/s. Bz varied between -6 and +4 nT, with the interplanetary magnetic field (IMF) directed away from the Sun (positive). Kp ranged from unsettled conditions to minor geomagnetic storming, while K Dourbes ranged from quiet conditions to minor storming.
The geo-environment is expected to remain under the influence of the CH HSS. Quiet to minor storm conditions are expected.
Today's estimated international sunspot number (ISN): 038, based on 11 stations.
