Bulletin

Solar activity was very quiet in the past 24 hours. No flares were observed. There is only one Catania sunspot group (51) observed on the visible side of the solar disk. Cactus detected one slow CME yesterday (01-Nov-2016 at 13:48 UT) with no impact for the Earth. Expanded to the low latitudes northern polar coronal hole may slightly disturb the geospace environment from today (02-Nov-2016) as suggested by WSA-ENLIL. 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. Variations of the solar wind parameters were low, though they slightly increased during the last few hours this morning (02-Nov-2016). Total Interplanetary Magnetic field (IMF) strength reached the value of 7nT, while Bz decreased till -7 nT. The solar wind speed decreased from 500 km/s till 420 km/s. Geomagnetic conditions were quiet (K Dourbes between 1 and 4; NOAA Kp between 1 and 4). The geomagnetic field is expected most probably to continue at quiet to unsettled levels, though some perturbations of IMF are possible during the mention above influence of the northern coronal hole influence.

Today's estimated international sunspot number (ISN): 000, based on 22 stations.
