Solar activity was very low with X ray flux remaining below B level. There is one inactive and stable spotted region (Catania group 80, NOAA region 2708) on the disk. The chance for any C class flares remains very low.
No Earth directed CMEs have been detected in coronagraph data.
The solar proton flux levels are at background values and are expected to remain so.
Soon after the start of the reporting period total magnetic field rose further to a peak of 17nT, with also the expected change into the negative sector around 13:30 UT. The Bz component was variable, reaching peaks down to -14nT. The magnetic field remained enhanced till around 1:30UT when it recovered to nominal 5-6nT values. Solar wind speed increased steadily over the period, reaching to over 650km/s after midnight and remaining over 600 km/s since then. The high speed stream is expected to persist over the next 48 hours.
Geomagnetic activity has reached moderate storm levels with an episode of NOAA Kp 6, although local K Dourbes did not reach above K=5, minor storm level. As total magnetic field in the solar wind has meanwhile declined to around 5-6nT, the peak of the geomagnetic activity should be passed. But active geomagnetic conditions are still to be expected as long as the high speed stream continues.
Today's estimated international sunspot number (ISN): 015, based on 23 stations.
