Solar activity is low with no flares reported during last 24 hours. All two active region, presently observed on the visible side of the solar disk have simple configuration of their photospheric magnetic field (alpha configuration). A fast CME with angular width of about 100 degrees erupted off the east solar limb at 23:36 UT on September 14 (as detected by CACTUS). STEREO-A data demonstrate that the event is initiated by the filament eruption at the backside of the Sun and will not affect the Earth. Solar protons have remained at background levels over the past 24 hours. Solar activity is expected to remain low over the next 24 hours with a small probability of C-class flares. Solar wind speed continued its gradual decline from about 350 km/s to its current value around 320 km/s. The magnitude of the Interplanetary Magnetic Field (Bt) has increased from 8 nT to 10 nT and remained stable, while Bz has been negative during last 24 hours, ranging between -5 nT and -8 nT. Mostly quiet to unsettled geomagnetic conditions were reported, with an isolated minor storming episode during the 21-23 UT interval reported by Dourbes. Geomagnetic conditions have been mostly quiet (K Dourbes between 1 and 4; NOAA Kp between 2 and 3). Active to minor geomagnetic storm conditions (K Dourbes = 3-4) are possible from today (15-Sep-2016) due to the increased values of the solar wind parameters.
