Bülletään

Over the past 24 hours solar activity has been low. The largest flares were two B3.9 class flares, produced by Active Region (AR) 2546 (Mcintosh class:Cho; Mag. type:Beta). All other ARs have been quiet. Solar protons have remained at background levels over the past 24 hours. There have been no Earth directed CMEs detected. 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 between 5 and 9 nT. The Bz component fluctuated between -5 and +6 nT, but has been largely 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 that may enhance solar wind speeds at the Earth.
