Bulletin

Solar activity was very low in the past 24 hours. No C-class flares, no Earth-directed CMEs were observed. There is only one NOAA H-alpha plage and one Catania sunspot group observed on the visible side of the solar disk. All visible filaments are stable. Solar proton flux intensity is expected to lie within the background levels. Solar activity is expected to be low with some probability for B-class flares. Solar wind parameters were at nominal values, with wind speed declining slightly from about 525 km/s to 475 km/s, while the magnitude of the Interplanetary Magnetic Field (Bt) fluctuated between 5 and 7 nT. Bz decreased from 1-2 nT till -5.5 nT during this morning (01-Nov-2016). In the past 24 hours, geomagnetic conditions have been quiet (K Dourbes between 1 and 4; NOAA Kp between 2 and 3). The geomagnetic field is expected to continue at quiet to unsettled levels till 03-Nov-2016.

Today's estimated international sunspot number (ISN): 012, based on 15 stations.
