Solar activity was very low in the past 24 hours. A B4.4 flare was observed today 20-Aug-2016 coming from the active region AR NOAA 2578 (peaking at 06:00 UT). Two additional active regions are presently observed on the visible side of the solar disc. Their photospheric magnetic field configuration is simple (alpha configuration). There is a transequatorial coronal hole observed presently on the visible solar disc which may become geoeffective in 3-4 days. No Earth-directed CME has been observed. Solar proton flux intensity is expected to lie within the background levels. Solar activity is expected to be low with small probability for B-class flares. The variations of the solar wind parameters were weak. Solar wind speed remained below 400 km/s during the last 24 hours. The magnitude of the Interplanetary Magnetic Field (Bt) elevated till 8 nT this morning (20-Aug-2016) and then it smoothly decreased till 5 nT. The Bz component demonstrated one variation within the interval 7nT : -4 nT and afterwards remained neutral. Geomagnetic conditions have been very quiet in the past 24 hours (K Dourbes between 1 and 3; NOAA Kp between 1 and 2). Geomagnetic activity is expected to continue at very low levels today (20-08-2016) and tomorrow (21-08-2016). Active to minor geomagnetic storm conditions (K Dourbes = 3-4) are possible later as a possible response to the transequatorial negative polarity coronal hole.
