公告

Several low-level C-class flares and one M-class flare were reported during last 24 hours. A long duration M1.8 flare, observed this morning, peaked at 06:41 UT. The M-class flare, as well as few C-class flares, originated from the Catania sunspot group 24 (NOAA AR 2222) which maintains beta-gamma configuration of its photospheric magnetic field. Currently available data give no indication about possible on disc signatures of the associated CME, therefore, we conclude that the M1.8 flare was most probably confined flare. Four out of ten currently numbered sunspot groups visible on the solar disc have beta-gamma configuration of their photospheric magnetic field and could be the source of the C-class flares and possible also an isolated M-class flare in the coming hours. No Earth directed CMEs were observed during last 24 hours. The Earth is currently inside a slow solar wind, with the speed of about 430 km/s. The interplanetary magnetic field is stable with the magnitude of about 5nT. The geomagnetic conditions are at the moment quiet to unsettled and expected to remain so in the following hours.
