Bülletään

Over the past 24 hours solar activity has been low. The largest flare was a B9.1 class flare. NOAA Active Region (AR) 2488 (Macintosh class:Cao; Mag. type:Beta) has been most active. AR 2488 has moved on to the West limb. ARs 2489 (Dho; Beta) and 2490 have shown some low levels of activity, and exhibited small amounts of flux emergence in HMI observations. There was a filament eruption around 15:00 UT yesterday (30-Jan-2016) near the Eastern limb, the resulting CME is not expected to interact with the Earth system. No Earth directed Coronal Mass Ejections (CMEs) have been detected. A positive polar coronal hole is currently positioned in the Western hemisphere of the Sun. Solar activity is expected to remain low over the next 24 hours with a high probability of C-class flares and a low probability of M-class flares. The solar wind speed has fluctuated between 260 and 300 km/s over the past 24 hours. The total magnetic field strength has fluctuated between 4 and 10 nT. The Bz component was largely negative, fluctuating between 0 and -7 nT. Geomagnetic conditions ranged between Kp index 0-3 (NOAA) and local K index 0-2 (Dourbes) over the past 24 hours. A positive polar coronal hole is currently positioned in the Western hemisphere of the Sun and the resulting high-speed stream (HSS) may enhance solar wind speeds.
