Bulletin

Solar activity was very low. The Sun was spotless. No earth- directed coronal mass ejections (CMEs) were observed in available coronagraphic imagery. The greater than 10MeV proton flux was at nominal levels.

Quiet flaring conditions are expected to continue.

Solar wind speed increased slightly from 380 km/s to 420 km/s at midnight, and has been steady since. Somewhat enhanced density (10/cm3) and negative Bz (up to -6 nT) were observed around midnight. Bz fluctuated between -6 nT and +2 nT, being mostly negative. The interplanetary magnetic field was mostly directed towards the Sun, with a brief positive interval (away) during the 21-24UT interval.

The geomagnetic field was at quiet to active levels (NOAA Kp). Mostly quiet to unsettled conditions are expected, until the arrival of the particle stream from the northern polar coronal hole extension expected for 13-14 March, which may result in active episodes.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 20 stations.
