Over the past 24 hours solar activity has been low. No C-class flares, no earth-directed coronal mass ejections (CME) have been observed. Active Region (AR) NOAA 2592 (Macintosh class:Bxo; Mag. type:Beta) has emerged over the East solar limb and has been most active, producing the B4.1 class flare, which peaked at 04:43 UT yesterday. Another AR 2591 has shown low levels of activity. Solar protons have remained at background levels over the past 24 hours. No Earth directed CMEs were detected. Solar activity is expected to remain low over the next 24 hours with a high chance of B-class flares and a low probability of C-class flares. The variations of the solar wind parameters were weak. Solar wind speed remained below 330 km/s during the last 24 hours. The magnitude of the Interplanetary Magnetic Field (Bt) smoothly elevated from 5 nT till 7 nT yesterday evening (15-Aug-2016). The Bz component remained neutral till 19:30 UT yesterday evening (15 Aug-2016) and then became positive. Geomagnetic conditions have been very quiet in the past 24 hours (K Dourbes between 0 and 2; NOAA Kp between 0 and 1). Geomagnetic activity is expected to continue at low levels today (16-Aug-2016) and tomorrow (17-Aug-2016). Active to minor geomagnetic storm conditions (K Dourbes between 3 and 4) are possible from 18-Aug-2016 as a possible response to the negative polarity coronal hole moving into a potentially geoeffective position.
