Bulletin

Solar activity was low with NOAA AR region 2665 (Catania group 36) producing B and C class flares. The strongest C1.2 flare was peaking at 20:31UT yesterday. The group evolved into a Beta-Gamma configuration, however it's magnetic complexity decreased during the period. Few slow and narrow (not Earth directed CMEs) were detected by Cactus during the past 24 hours. A small negative polarity southern coronal hole may create enhanced solar wind conditions on the day 3 (14-Jul-2017). Solar proton flux values are at background levels and expected to remain so. More C-class flares can be expected (and less likely M-flares). Solar wind parameters reflected a fainting influence of a high speed stream from an equatorial coronal hole. Total magnetic field remained below 5 nT, while Bz component was fluctuating between +/-3 nT over the past 24 hours. Solar wind speed gradually decreased from 620 km/s till 510 km/s. Geomagnetic conditions were very quiet. Planetary index Kp decreased from 2 to 1, while the local K index (Dourbes) was fluctuating between 1 and 3 over the past 24 hours. The geomagnetic field is expected to be at quiet levels today and tomorrow, while on the day 3 (14-Jul-2017) active geomagnetic conditions can be expected due to the influence of a small negative polarity southern coronal hole.
