COMMENT: Catania sunspot group 39 (NOAA AR 1484) produced a C1.2 flare
peaking at 00:27 UT today. More C-class flares can be expected from this
group, as well as from recently emerged Catania sunspot group 47 (NOAA
AR 1488). The post-shock solar wind flow was followed by a fast solar
wind stream (with the speed reaching 700 km/s) from a small low-latitude
coronal hole in the southern hemisphere. Due to high interplanetary
magnetic field (IMF) magnitude (that reached 15 nT), active geomagnetic
conditions (K = 4) were reported by Dourbes and IZMIRAN and minor storm
conditions (K = 5) were reported by NOAA. Currently the solar wind speed
is still elevated (around 620 km/s), but the IMF magnitude decreased to
average values (around 4 nT). We therefore expect quiet geomagnetic
conditions.

TODAY'S ESTIMATED ISN  : 055, BASED ON 13 STATIONS.
