Bulletin

The solar activity has been quiet over the past 24 hours. The X-ray flux remained below B-level, and the visible solar disc is spotless. A new plage has now turned over the East limb (associated with the old NOAA Region 2741), but does not show any more spots or strong activity so far. Solar activity is expected to remain at low levels for the next 24 hours.

No Earth directed Coronal Mass Ejection (CME) has been detected in the available coronagraph imagery. The greater than 10 MeV solar protons flux remained at nominal levels over the past 24 hours and is expected to remain so.

Solar wind environment near Earth show the ambient background and slow solar wind speed regime. Solar wind speed is about 350 km/s. The total interplanetary magnetic field strength remained below 4 nT. The Bz component was ranging between -2.3 nT and -2.6 nT. The solar wind parameters are expected to remain at the nominal levels.

The geomagnetic conditions have been mostly quiet and are expected to remain quiet.

Today's estimated international sunspot number (ISN): 000, based on 23 stations.
