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 2MeV electron flux was between nominal and moderate levels over the past 24 hours and is expected to remain so for the next 24 hours.

The solar wind speed near Earth showed a generally increasing trend with values ranging between 360 and 450 km/s (DSCOVR) over the past 24 hours. The Interplanetary Magnetic Field (IMF) was predominantly oriented towards the Sun (phi angle in the negative sector) with the magnitude varying between 0 and 6 nT. Bz ranged between -5 and +5 nT. 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 affect Earth from late on Mar 29 until Mar 31.

Quiet to unsettled geomagnetic conditions were registered for the past 24 hours (K Dourbes and NOAA Kp recorded values 0-3 and 0-2, respectively). Unsettled geomagnetic conditions are expected for the next 24 hours, with active conditions (K Dourbes = 4) possible on Mar 30 and 31.

Today's estimated international sunspot number (ISN): 000, based on 21 stations.
