A shock was seen in the solar wind at 01:34 UT marking the arrival of the CME from 7
December. The speed jumped from 450 km/s to 560 km/s and the magnetic field from 6 nT
to 16 nT. It did not have long lasting negative Bz embedded in it, therefore only
unsettled conditions were seen locally (K Dourbes =3) and active at planetary levels
(Kp = 4).
