Solar activity was at very low levels, with only one B-class flare produced in the last 24 hours. NOAA Active Region (AR) 2842 (Catania sunspot group 17), and NOAA AR 2841 continued to decay. Catania sunspot group 18 has increased in complexity and is expected to increase its activity. For the next 24 hours the solar activity is expected to remain low with a small change of a C-class flare.

A back-sided halo CME was detected in the last 24 hours, but it is not expected to be Earth-directed.

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 was between 310 and 370 km/s during the last 24 hours. The total magnetic field varied between 1 and 12 nT in the last 24 hours. The Bz was predominantly negative during the last 24 hours, with values varying between 3 and -8 nT. The interplanetary magnetic field phi angle varied between positive and negative values during the last 24 hours. The solar wind conditions are expected to continue to reflect a slow solar wind regime for the next 24 hours.

Geomagnetic conditions were quiet both globally (NOAA Kp index 1) and locally (K Dourbes 0-2) over the past 24 hours. They are expected to remain quiet for the next 24 hours.
