Over the past 24 hours solar activity has been very low. The visible solar disc was spotless and no significant flares have been recorded. No Earth directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph imagery. The greater than 10MeV proton flux remained at background levels over the past 24 hours. Solar activity is expected to remain very low over the next 24 hours.

The solar wind speed gradually decreased from around 370 km/s to 330 km/s over the first half of the period, before recovering slightly at the end of the period to a speed of around 340 km/s. The total magnetic field strength fluctuated over the last 24 hours between 1.2 and 5.9 nT. The Bz component ranged between approximately -4 and +4 nT. The phi angle was predominantly in the negative sector.

Geomagnetic conditions have been quiet over the past 24 hours, with Kp index (NOAA) registering 1 for the entire period and local K index (Dourbes) ranging between 1 and 2, with one short interval of k equal to 3 at 9 UT. Quiet geomagnetic conditions are expected over the next 24 hours, with the possibility of isolated unsettled periods due to the weak solar wind stream associated with a series of small negative polarity coronal holes.
