Solar activity was very low. Former NOAA actve region 2703 decayed to an area of plage. 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 remain so. Solar wind parameters variations were at background levels. Solar wind speed as registered by DSCOVR decreased from about 430 till 400 km/s. The Interplanetary Magnetic Field (IMF) was below 5 nT. Bz component varied mainly between -3 and 3 nT. Quiet geomagnetic conditions (K Dourbes between 1 and 2; NOAA Kp between 1 and 2) were registered in the past 24 hours. Mostly quiet geomagnetic levels (K Dourbes < 3) are expected on April 3 and 4. Unsettled conditions are expected on April 5 due to the possible influences of a high speed stream coming from the polar-connected positive polarity coronal hole.
Today's estimated international sunspot number (ISN): 000, based on 21 stations.
