Bulletin

Over the past 24 hours solar activity has been low. No significant flares have been recorded. No Earth directed Coronal Mass Ejections (CMEs) have been detected. There's a small northern coronal hole extending to lower latitudes in the western hemisphere that may increase solar wind speeds in a couple of days. Solar activity is expected to remain low over the next 24 hours with a low probability of C-class flares and a very low probability of M-class flares. The solar wind speed has slowly increased from around 320 km/s to 400 km/s over the past 24 hours. The total magnetic field strength has fluctuated around 7 nT. The Bz component fluctuated between -7 nT and +7 nT. Geomagnetic conditions ranged between Kp index 1-2 (NOAA) and local K index 1-2 (Dourbes) over the past 24 hours. Geomagnetic conditions are expected to be quiet but the increasing solar wind speeds may enhance geomagnetic conditions.
