Bülletään

The solar activity was quiet over the past 24 hours and no flare has been recorded. A small sunspot has recently emerged (NOAA active region 2693) on the north-west quadrant of the visible disc. Quiet flaring conditions are expected for the next 24-hour period with possible but not very likely C-class flares from the newly emerged sunspot.

No Earth directed Coronal Mass Ejection has been observed. The greater than 10 MeV solar protons flux remained at nominal levels over the past 24 hours and is expected to remain so.

The Earth was within the slow solar wind speed regime over the past 24 hours. The solar wind speed was ranging between 350 and 400 km/s. The interplanetary magnetic field magnitude was below 5 nT, and the Bz component was ranging from -4 to 4 nT. A northern polar coronal hole extending down to latitude 20 degrees is currently facing Earth. Solar wind enhancements and high speed streams associated with the coronal hole are not expected to arrive before Jan 08.

The geomagnetic conditions were quiet and it is expected to remain quiet as the Earth is within the slow solar wind speed stream. Disturbance of the geomagnetic conditions are anticipated on Jan 08 due to the arrival of the high speed streams associated with the coronal hole.
