Skrót wiadomości

Solar flaring activity has slightly increased, with seven lower C-class flares (strongest C1.8) during the past 24 hours. The NOAA active regions (AR) 2490 (Catania 16), 2492, 2493 and a region currently rounding the East limb were responsible for this activity. Two new (yet unnumbered) regions are developing quite rapidly, near S10E15 and S08W20. A filament eruption was observed SouthEast of the disk center from 8h UT on February 3. The associated CME only left near 16h UT (first observation LASCO/C2) and was very narrow. A rather faint and slow CME (245km/s estimated by CACTus) lifted off at 9h36 UT on February 3 (first measurement at LASCO/C2), propagating to the SouthWest. The source of this CME is currently unclear, but will be analyzed further. More flaring at the C-level is expected, with a slight chance for an M-class flare. The solar wind speed ranged between 350 and 450 km/s, showing a slight increase. The magnitude of the magnetic field was around 10 nT, with a mainly positive Bz component.

Geomagnetic conditions were mainly quiet (K=0-2), both at the local (Dourbes) and global level (NOAA estimate). This situation is expected to continue, with a slight chance for time slots of unsettled to active conditions.
