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 in the past 24 hours and is expected to stay at nominal levels in the next 24 hours. The greater than 2MeV electron flux is enhanced (crossing the event threshold of 1000 pfu between 12:00 and 19:45 Mar 25). It is expected to remain enhanced on Mar 26 - 27 and then to slowly return to nominal values.

The solar wind speed near Earth ranged between 350 and 420 km/s (DSCOVR) over the past 24 hours. The Interplanetary Magnetic Field (IMF) was predominantly oriented towards the Sun and its magnitude varied between 0 and 6 nT. Bz ranged between -3 and +4 nT. Background solar wind conditions are expected for the next 24 hours. The solar wind associated with an extension to the southern polar coronal hole, which began to cross the central meridian on Mar 26, is expected to impact Earth from late on March 28.

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

Today's estimated international sunspot number (ISN): 000, based on 24 stations.
