The solar wind is still stable in the range 600-650km/s, with a weak IMF (5nT). Some southward fluctuations of the Bz component of the IMF induced active geomagnetic conditions (minor storm at high latitudes) over the last few hours, but this geomagnetic activity will start to decrease later today and tomorrow, as the fast solar wind stream starts to decay, by tomorrow June 9. TODAY'S ESTIMATED ISN : 037, BASED ON 07 STATIONS.
