Bülten

Solar activity was at very low levels. The Sun was spotless for the 12th consecutive day (SILSO). No coronal mass ejections (CMEs) were observed over the last 24 hours. The greater than 10 MeV proton flux was at nominal values. A narrow extension of the positive polarity northern polar coronal hole (CH) has transited the central meridian.

Solar activity is expected to remain at very low levels.

Solar wind speed showed a generally declining trend, from about 355 km/s at the beginning of the period to 315 km/s at the end (DSCOVR). Bz ranged from -4 to +4 nT. The interplanetary magnetic field remained chiefly directed towards the Sun (negative sector). Quiet geomagnetic conditions were observed.

Quiet geomagnetic conditions are expected to continue, until the arrival of the wind stream associated with the extension of the northern polar CH, currently expected for late on 28 or on 29 December. This may result in active geomagnetic conditions, a minor storming interval is not excluded.
