Bulletin

The solar activity has been quiet over the past 24 hours. The visible solar disc is spotless, and no significant flare has been recorded. Quiet flaring conditions are expected for the next 24-hour period.

No Earth directed Coronal Mass Ejection has been observed over the past 24 hours. 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 ranged between 411 and 472 km/s; The interplanetary magnetic field strength fluctuated between 1.4 and 7.5 nT and the southward magnetic component between -5.8 and 6.2 nT. The solar wind conditions are expected to remain the same for the next 24 hours and start to slowly decrease afterwards.

The geomagnetic conditions were quiet to unsettled and are expected to remain the same as Earth remains under the influence of the enhanced solar wind conditions associated to the Coronal Hole.

Today's estimated international sunspot number (ISN): 000, based on 14 stations.
