COMMENT: Several C flares occurred in the past 24 hours. Most of them from
the newly emerged NOAA active region 3079 in the South as reported
yesterday. The strongest flare was a C6.8 flare peaking at 7:31UTC.
This bipolar region developed a dominant trailing spot and exhibits mixed
polarity field in the intermediate area. The unipolar active regions NOAA
3071 and 3074 were stable while unipolar region NOAA 3078 showed some
growth and became bipolar. The bipolar NOAA active region 3077 has decayed
just as the newly numbered NOAA active region 3080 which was shortlived.
The now bipolar region NOAA 3076 in the north has grown following the new
flux emergence reported yesterday. Another bipolar region has recently
emerged rapidly in the north east (NOAA active region 3081).
All in all, C class flaring is very likely with now also chances for M
class flaring.

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 or around the threshold in the next 24
hours.
The 24h electron fluence was at moderate levels and is expected to be at
moderate levels with a slow decreasing trend.

Declining high speed Solar wind conditions were recorded. Solar wind speed
decreased from around 575 to just over 500 km/s while the interplanetary
magnetic field strength varied around 5nT. The magnetic field orientation
showed mostly a connection to a positive sector (field away from the Sun).
Over the next 24 hours Solar wind speed is expected to continue the
decreasing trend and slowly return towards slow Solar wind conditions.

Geomagnetic conditions were quiet to unsettled (both local K Dourbes and
NOAA Kp 1-3).
Geomagnetic conditions are expected to be quiet to unsettled over the next
days.
