Bulletin

Solar activity was very low. No flares, no Earth-directed CMEs were observed. There are 2 stable filaments on the visible side of the solar disk. Solar proton flux intensity is expected to lie within the background levels. Quiet flaring conditions are expected to continue, with a small chance of an isolated B-class flare. Solar wind parameters variations were at the background level. Solar wind speed decreased from about 420 km/s to its current values near 370 km/s. Total Interplanetary Magnetic field strength varied between 3 and 7 nT, while Bz fluctuated between -3 and +3 nT and was mostly positive. Solar wind parameters are expected to remain at near background levels for the next 2 days. Geomagnetic conditions were active to quiet during this period (K Dourbes between 5 and 1; NOAA Kp between 4 and 1). The geomagnetic field is expected most probably to continue at quiet levels today 04-Nov-2016 and tomorrow 05-Nov-2016.

Today's estimated international sunspot number (ISN): 027, based on 13 stations.
