Bülletään

Solar activity was at very low levels. The Sun was spotless. 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 nearly finished its transit of the central meridian.

Solar activity is expected to remain at very low levels.

Solar wind speed varied between 340 and 370 km/s (DSCOVR). Bz ranged from -5 to +4 nT. The interplanetary magnetic field remained primarily directed towards the Sun (negative sector). Quiet geomagnetic conditions were observed.

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