Solar flaring activity was low and consisted of just two C1 flares this morning from the bipolar region that was numbered yesterday (Catania sunspot group 9, NOAA active region 3077). The region seemed to experience some opposite polarity flux emergence near the trailing spots. The other regions on disc were all stable or decaying, with the exception of some flux emergence immediately to the north of the unipolar Catania sunspot group 8 (NOAA active region 3076), late in the period. Flaring at C level is not very likely but remains possible over the next days.

No Earth-directed coronal mass ejections (CMEs) were detected in the available coronagraph imagery.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours and is expected to remain so in the next days. The greater than 2 MeV electron flux remained above the 1000 pfu threshold and is expected to remain above the threshold again in the next days. The 24h electron fluence was at moderate levels and is expected to be at moderate levels and possibly reaching high levels in the next 24 hours, then followed by a slow decreasing trend over the next days.

Earth continues to be under high speed Solar wind conditions. Solar wind speed was between 520-600km/s with a decreasing trend. The interplanetary magnetic field had a strength of around 5nT with a variable north south orientation and the magnetic field orientation showed connection to a positive sector (field away from the Sun). High speed Solar wind conditions are expected to continue at least today and into tomorrow, but should show an overall decreasing trend.

Geomagnetic conditions were quiet to unsettled (both local K Dourbes and NOAA Kp 2-3). Quiet to unsettled geomagnetic conditions are expected over the following days, with initially still a possibility for an isolated active period while the high speed stream Solar wind conditions are declining.
