Solar activity was very low in the past 24 hours. No flares, no Earth-directed CMEs were observed. Four active regions are presently observed on the visible side of the solar disc. Solar proton flux intensity is expected to lie within the background levels. Solar activity is expected to be low with some probability for C-class flares.

Solar wind parameters were at nominal values, with wind speed declining slightly from about 375 km/s to 330 km/s. The magnitude of the Interplanetary Magnetic Field (Bt) increased from +5 nT to 13 nT, while Bz increased from -4 nT till +12 nT during this morning (12-Sep-2016) due to the weak influence of a positive polarity coronal hole. The interplanetary magnetic field (IMF) was mostly directed away from the Sun (positive). In the past 24 hours, geomagnetic conditions have been quiet (K Dourbes between 1 and 3; NOAA Kp between 1 and 3). Active to minor geomagnetic storm conditions (K Dourbes = 3-4) are possible from today (12-Sep-2016) due to the increased variations of the solar wind parameters.
