Bulletin

Over the past 24 hours solar activity has tendency to increase with respect to the previous 2 days. Two slow Coronal Mass Ejections (CMEs) detected yesterday at 15:24 UT and 23:28 UT are not expected to affect the Earth. Filament eruption has been occurred today at 08:24 UT at the Eastern limb. There are two ARs currently on the solar disk; AR 2528 (Macintosh class:Gro; Mag.type:Beta) and one returning AR, which has just appeared at the Eastern limb. This region produced two C class flares yesterday and three more today. The largest flare was a C1.9 class flare, which peaked at 11:13 UT this morning. 10.7 cm radioflux index slightly increased with respect to the previous days. Solar protons have remained at background levels over the past 24 hours. Solar activity is expected to remain low over the next 24 hours, however the probability of C-class flares to occur slightly increased with respect to previous days. The total magnetic field strength in solar wind has increased slightly over the past 24 hours, from 5 nT to till 10 nT. The Bz component also increased from 0 to 7 nT over the past 6 hours and remains positive. The systematic significant growth of solar wind density over last 24 hrs is also observed. The solar wind speed has remained stable varying around 400 km/s over the past 24 hours. Geomagnetic conditions ranged between Kp index 1-3 (NOAA) and local K index 1-3 (Dourbes) over the past 24 hours. Geomagnetic activity is expected to remain low the next day. We can expect to encounter a high speed stream in approximately 1 days time.
