Bülletään

During the last 24 hours, Catania sunspot group 35 (NOAA AR 1800) produced three weak C-class flares, the strongest one being the C1.8 flare peaking at 21:43 UT yesterday. We expect more C-class flares in this group, but the probability for flaring at the M-level is low. A filament eruption at the solar central meridian (between Catania sunspot groups 35 and 44) starting around 02:00 UT today was accompanied by coronal dimmings and a post- eruption arcade, as shown by the SDO/AIA data. However, no corresponding CME was detected by SOHO/LASCO or STEREO/COR. The Earth is currently inside a slow (around 320 km/s) solar wind flow with average (around 5 nT) interplanetary magnetic field magnitude. We expect quiet geomagnetic conditions until the arrival of the interaction region between the slow and fast solar wind flows later today (followed by the fast flow from the equatorial coronal hole), which may result in active geomagnetic conditions.
