Bulletin

The solar activity has been quiet over the past 24 hours. The X-ray flux remains below B-level. Two regions show some mild activity, but no sunspots are clearly visible on the disc. 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.

Solar wind speed fluctuated around 350 km/h and 450 km/h, the total interplanetary magnetic field strength was steady and remained below 6.5 nT. The Bz component fluctuated between -5 nT and 5 nT. The solar wind parameters are expected to remain slightly enhanced due to several small patchy equatorial coronal holes (negative polarity) that dominate the current space weather conditions for the following days with a wind speed ranging from nominal values (around 350 km) to 400-450 km/s.

The geomagnetic conditions were quiet over the past 24 hours. The geomagnetic conditions are expected to remain mostly quiet. In response to the slightly enhanced interplanetary magnetic field due to small patchy equatorial coronal holes and possible prolonged period of southward directed Bz component, short periods of unsettle are possible.

Today's estimated international sunspot number (ISN): 000, based on 15 stations.
