Bulletin

Over the past 24 hours solar activity has been quiet. No significant flares have been recorded. No Earth directed Coronal Mass Ejections (CMEs) have been detected. There are no significant coronal holes or filaments. Solar activity is expected to remain low over the next 24 hours with a low probability of C-class flares. The solar wind speed has fluctuated between 330 and 360 km/s over the past 24 hours. The total magnetic field strength has fluctuated around 3 nT. The Bz component has fluctuated around 0 nT, between -2 and +3 nT, but has been primarily positive. Geomagnetic conditions ranged between Kp index 1-2 (NOAA) and local K index 0-2 (Dourbes) over the past 24 hours. Geomagnetic conditions are expected to be mainly quiet, however, a patchy open field/quiet sun region in the central latitudes may enhance solar wind speeds slightly over the next few days.

Today's estimated international sunspot number (ISN): 000, based on 16 stations.
