There are no sunspot regions on the visible hemisphere of the Sun and flaring level is very low. The chance for a C flare in the next 24 hours is estimated at 3%.

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 near Earth was enhanced due to the continued influence of a negative polarity coronal hole (CH) wind stream. Solar wind speed measured by DSCOVR varied between about 440 and 560 km/s in the past 24 hours. The Interplanetary Magnetic Field (IMF) was predominantly directed towards the Sun and its magnitude varied between about 1 and 8 nT. There were no prolonged intervals with Bz below -5 nT.

Quiet to active geomagnetic conditions (K Dourbes between 1 and 4; NOAA Kp between 2 and 3) were registered in the past 24 hours. Quiet to active levels (K Dourbes < 5) are expected on March 27 and 28 in response to the continuing CH wind stream, with a slight chance for minor storm intervals (K Dourbes = 5). Minor storm levels are possible on March 29, as a high speed stream from a positive polarity, northern polar CH is expected to arrive at Earth.
