NOAA AR 2665 (the only visible active region on the disk) produced multiple B class flares and one C1.5 flare over the past 24 hours, with peak 00:31 UT today. This region continues to grow, more C-class flares can be expected (and less likely M-flares). The AR development (rotation of the leading spot and evolution of intermediate area between 2 main spots) suggests a buildup of magnetic shear and NE-SW neutral line, which eventually may lead to the filament formation. No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar protons have remained at background levels over the past 24 hours. Solar wind parameters reflected a fainting influence of a high speed stream from an equatorial coronal hole. Total magnetic field decreased from about 15 to 7 nT, while the Bz component was between +/-2 nT (starting from 00 UT today). Solar wind speed remained below 600 km/s. Geomagnetic conditions were ranged from active to quiet. Planetary index Kp decreased from 4 to 1, while the local K index (Dourbes) was almost constant K =3 over the past 24 hours. The geomagnetic field is expected to be at quiet to active levels.
