Bülletään

Solar activity was at very low levels, no flares, no Coronal Mass Ejections (CMEs) were observed during the past 24 hours. NOAA 2665 decayed further and was quiet. New NOAA AR 2666 was numbered today but remained inactive. Solar protons have remained at background levels over the past 24 hours. One negative polarity southern coronal hole (small in size) will move into the geoeffective position from tomorrow (14-July-2017). Flaring activity is expected to be on B-level, C flares are also not excluded. Solar wind speed gradually declined from 515 km/s till 395 km/s. Bz was relatively stable between -3 and +3 nT. The interplanetary magnetic field was below 4 nT. The geomagnetic field was at quiet levels (planetary index KP NOAA from 0 to 1; local index K Dourbes from 1 to 3). Geomagnetic conditions are expected to remain quiet at least till midnight today (13-July-2017). From tomorrow active geomagnetic conditions are possible due to the mentioned above negative coronal hole possible geoeffectivness.
