COMMENT: Solar activity slightly increased during the period. Two C-class
flares were recorded: a C8.1 flare peaking at the beginning of the period
(13:47 UT), and then a C1.7 event peaking at 14:39 UT. Both flares
originated from NOAA 2699 active region, which developed it's magnetic
configuration from beta to beta-gamma. Proton flux levels are at background
values and are expected to remain so. No Earth-directed CMEs were observed.
C-class flaring remains possible, with a small chance on an isolated
M-class flare.
Solar wind speed decreased from 425 km/s till at 390 km/s during the
period. Interplanetary magnetic field magnitude is below 5 nT. Geomagnetic
conditions have been very quiet. A low latitude extension of the northern
polar coronal hole has still a slight chance to affect geomagnetic
environment in the next 48hrs, unsettled conditions can be expected then.
TODAY'S ESTIMATED ISN : 024, BASED ON 13 STATIONS.
