Skrót wiadomości

The solar activity has been quiet over the past 24 hours. The visible solar disc was spotless, and no significant flare has been recorded. A new bipolar sunspot group (Catania sunspot group 2) has emerged today, no significant flare has been recorded. Flaring conditions are expected to increase with as small change of C-class flare.

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 solar wind measurements remained under the influence of the enhanced solar wind associated with the Coronal Hole (which reached the central meridian on November 27). The wind speed decreased to 415 km/s (December 4 around 13:00 UT), then re-increased and reached 500 km/s on December 4, around 19.00 UT. The interplanetary magnetic field strength fluctuated between 1.5 and 7 nT and the southward magnetic component between -4.8 and 5.2 nT. The solar wind parameters are expected to start to decrease to the slow solar wind regime. A large south polar coronal hole (of negative polarity) that extended up to latitude 10 degree North is currently facing Earth. The solar wind parameters are expected to be enhanced due to the fast solar wind associated with this coronal hole on the afternoon of December 7.

The geomagnetic conditions were quiet. The conditions are expected to be mainly quiet as the Earth is entering the slow solar wind speed regime. The geomagnetic conditions will then become more active due to the arrival of the fast solar wind.
