Bulletin

There are no sunspot regions on the visible hemisphere of the Sun but the loops of a far side active region are rotating into view at the East limb. Flaring level is very low. The chance for a C flare in the next 24 hours is estimated at 10%, mainly from the region behind the East limb.

No Earth-directed Coronal Mass Ejections (CMEs) were observed in 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.

Solar wind speed measured by DSCOVR further decreased from about 430 to 340 km/s in the past 24 hours. The Interplanetary Magnetic Field (IMF) was predominantly directed towards the Sun and its magnitude varied between about 0 and 6 nT. There were no prolonged intervals with Bz below -5 nT.

Quiet geomagnetic conditions (K Dourbes between 0 and 2; NOAA Kp between 0 and 1) were registered in the past 24 hours. Due to the expected arrival of a high speed stream from a positive polarity, northern polar coronal hole, active geomagnetic levels (K Dourbes = 4) are possible on March 29, 30 and 31, with a chance for minor storm intervals (K Dourbes = 5).
