Skrót wiadomości

Solar activity was very quiet in the past 24 hours. No flares were observed. The only numbered NOAA active region (AR) 2619 observed on visible side of the solar disk has simple magnetic configuration. Another small sunspot group, observed this morning (20-Dec-2016) by UCCLE-USET, Locarno and Kanzelhohe Observatories, by its high latitude (-23 degrees) and reverse polarity belongs to the next solar cycle 25. No Earth directed CMEs were observed. The large equatorial coronal hole with the low latitude extend that crossed central meridian yesterday afternoon (18-Dec-2016) is expected to disturb significantly the geospace environment from tomorrow evening (21-Dec-2016). 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 very low. Total Interplanetary Magnetic field (IMF) strength varied between 3 and 7 nT, while Bz varied between -3.5 and 3.5 nT. The solar wind speed decreased from 370 km/s till 340 km/s. Geomagnetic conditions were ranged from quiet to moderate (K Dourbes between 0 and 3; NOAA Kp between 1 and 2). The geomagnetic conditions are presently quiet to unsettled. We expect active conditions tomorrow evening (21-Dec-2016) due to expected arrival of the fast solar wind coming from the mentioned above large equatorial coronal hole.
