Posted - 22 Mar 2006 : 07:47:45 AM Catania sunspot group 15 (NOAA AR 0862) has grown up further and developed a beta-gamma configuration of the photospheric magnetic field. C2.5 and C1.3 flares (peaking at 09:44 UT and 12:04 UT respectively) occurred today in this group. More C-flares are possible, and there is a low probability for an M-flare. The solar wind speed decreased down to around 600 km/s and the magnetic field remains at the average level. We expect quiet geomagnetic conditions for the next 48 hours.
