Bulletin

The solar activity has been quiet over the past 24 hours. The X-ray flux remains below B-level, and the visible solar disc is spotless. Solar activity is expected to remain at low levels.

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 parameters continued to slowly return toward nominal values. The wind speed decreased from 455 to 395 km/s. Total interplanetary magnetic field strength was below 6 nT. The southward magnetic component remained between -4.5 and 4.7 nT. The solar wind speed is expected to continue to decrease and remain at ambient background and slow solar wind speed regime.

The geomagnetic conditions were quiet and are expected to remain quiet during the following next 24-hour period.

Today's estimated international sunspot number (ISN): 000, based on 18 stations.
