Bulletin

Solar flaring activity was at very low levels. No significant flares have been recorded. Solar activity is expected to remain at very low levels.

No Earth directed Coronal Mass Ejections (CMEs) were observed in the available coronagraphic imagery.

The greater than 10 MeV proton flux was at nominal levels over the past 24 hours and is expected to stay at nominal levels for the next 24 hours. The greater than 2 MeV electron flux was at moderate levels the past 24 hours. It is expected to remain as such for the next 24 hours.

The solar wind speed near Earth oscillated between the values of 405 to 460 km/s (DSCOVR). The Interplanetary Magnetic Field (IMF) was predominantly oriented towards the Sun (phi angle in the negative sector) with some transient positive features. Bz varied between -5 and +6 nT. The magnitude of the magnetic field varied between 2 and 8 nT. For the next 24 hours the solar wind speed is expected to stay at those levels, but some enhancements are expected from late April 5 due to arrival of the solar wind associated with the positive polarity coronal hole crossing the central meridian on Mar 31.

Quiet to unsettled geomagnetic conditions were registered for the past 24 hours (K Dourbes recorded values 0-3 and NOAA Kp 0-2). Quiet to unsettled (K Dourbes = 3) geomagnetic conditions are expected for the next 24 hours.

Today's estimated international sunspot number (ISN): 000, based on 25 stations.
