Solar activity was at very low levels. NOAA Active Region (AR) 2842 (Catania sunspot group 17) produced a B-class flare, while NOAA AR 2841 (Catania sunspot group 16) did not produce any noticeable activity. The newly-emerged Catania sunspot group 18 has a simple configuration and is not expected to produce significant activity. Overall, the solar activity is expected to be very low over the next 24 hours with a low probability of a C-class flare.

No Earth directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph imagery.

The greater than 10 MeV proton flux was at nominal levels over the past 24 hours and is expected to remain so for the next 24 hours. The greater than 2 MeV electron flux remained below the 1000 pfu alert threshold and is expected to remain below this level during the next 24 hours. The 24h electron fluence was at nominal levels and is expected to remain so.

The solar wind speed 290 and 370 km/s in the last 24 hours. The total magnetic field was between 1.4 and 10 nT, while the Bz varied between -7.7 and 5.8 nT. The interplanetary magnetic field phi angle was predominantly in the negative sector (directed towards the Sun). The solar wind conditions are expected to continue to reflect a slow solar wind regime for the next 24 hours.

Geomagnetic conditions were quiet to unsettle both globally and locally (NOAA Kp and K Dourbes 1-3) over the past 24 hours. They are expected to become quiet for the next 24 hours, as no geomagnetic disturbances are expected.
