Sluneční záblesky : Quiet conditions (<50% probability of C-class flares)
Geomagnetická situace : Quiet (A<20 and K<4)
Sluneční protony : Quiet
Komentář : The only active region, observed on the visible side of the Sun
since morning of January 21, was numbered today and it is now NOAA AR 2733.
During last 24 hours it has increased in size and complexity, presently
having beta configuration of its photospheric magnetic field configuration.
The flaring activity remained low, despite the presence of NOAA AR 2733. We
expect such activity to persist in the coming hours, with a low probability
for an isolated C-class flare.
There were no Earth directed CMEs reported during last 24 hours and the
solar protons remained at the background level.
The solar wind speed started to increase this morning and it is presently
about 430 km/s. The interplanetary magnetic field magnitude is about 8 nT.
The interplanetary magnetic field, and its Bz component, increased and
started to oscillate at about 23:30 UT on January 22, indicating arrival of
the compression region between the slow and fast solar wind associated with
the expected fast flow from the equatorial coronal hole which reached
central meridian in the morning of January 19.
The longer intervals of negative values of the Bz component of the
interplanetary magnetic field have induced unsettled geomagnetic conditions
around the midnight of January 22 and early this morning. Local station at
Dourbes reported K=3. We expect unsettled to possible active geomagnetic
conditions in the coming hours.
