Bulletin

Solar activity was very low in the past 24 hours. No flares, no coronal mass ejections were observed. One NOAA Halpha plages 2619 and one NOAA active region (AR) 2620 are rotating across the west solar limb, while one returning NOAA AR is expected to appear at the east solar limb in the next 24 hours. Solar protons have remained at background levels. Solar activity is expected to remain low over the next 24 hours with a small chance of B-class flares. The solar wind speed was stable over the past 24 hours, varying around 630 km/s. The total magnetic field strength has fluctuated between 7.5 nT and 4.5 nT. The Bz component has fluctuated between -6 nT and +7 nT. Geomagnetic conditions were ranged between Kp index 2-4 (NOAA) and local K index 1-4 (Dourbes), with the singular enhance value from Dourbes K=4 (starting at 12:00 UT today, 25-12-2016). The solar wind variations are still enhanced due to the fast solar wind stream from the coronal hole, as a consequence geomagnetic conditions are expected to be active to unsettled to for the next two days (Kp index <= 4). A minor storm (Kp = 5) is not excluded.
