The in situ observations show the arrival of the shock wave, this morning at 01:24
UT. The magnetic field magnitude, currently about 6 nT, showed simultaneous increase
with the solar wind speed (maximum value reached was 390 km/s), density and the
temperature.
The solar origin of the observed shock is presently unclear and more will be reported
later. Currently the Bz component of the interplanetary magnetic field is positive
and no geomagnetic disturbance is reported (K=2 and Kp=2, as reported by Dourbes and
NOAA, respectively).
