Bülletään

Over the past 24 hours solar activity has been low. The largest flare was a B5.1 class flare, produced by Active Region (AR) 2544 (Macintosh class:Cso; Mag. type:Beta). All other ARs have been quiet. AR 2544 has exhibited some flux emergence and cancellation in HMI observations, which may lead to further flares. Solar protons have remained at background levels over the past 24 hours. Solar activity is expected to remain low over the next 24 hours with a small probability of C-class flares. The solar wind speed has remained around 450 km/s over the past 24 hours. The total magnetic field strength has fluctuated around 5 nT. The Bz component fluctuated between -5 and +5 nT, but has been mainly positive. Geomagnetic conditions ranged between Kp index 1-3 (NOAA) and local K index 1-3 (Dourbes) over the past 24 hours. A large Northern positive polar coronal hole is currently positioned in the Western hemisphere of the Sun and may enhance solar wind speeds at the Earth. The CME produced at 15:24 UT on 15-May-2016 has shown no influence at the Earth.
