The solar activity has been quiet over the past 24 hours. The visible solar disc is spotless and the X-ray flux is below B-level. The solar activity is expected to remain at low levels over the next 24 hours.

No Earth-directed coronal mass ejections (CMEs) was observed in the available coronagraph imagery.

The greater than 10 MeV proton flux was at nominal levels over the past 24 hours and is expected to remain so for the next 24 hours. The greater than 2 MeV electron flux was below the 1000 pfu threshold in the past 24 hours and is expected to remain so during the next 24 hours. The 24h electron fluence is at normal levels in the last 24 hours and is expected to stay at normal levels for the next 24 hours.

The solar wind parameters (ACE and DSCOVR) were mostly at background levels: The solar wind speed ranged between 350 km/s and 410 km/s . The interplanetary magnetic field magnitude was below 6.0 nT, and Bz components varied between -4.3 nT and 4.0 nT. The high-speed streams associated with the equatorial coronal hole (positive magnetic polarity and facing Earth on Mars 31) is expected to slightly enhanced the solar wind conditions near Earth later today and tomorrow on April 2 and 3.

Geomagnetic conditions were quiet (Kp and K-Dourbes: 0-2). Unsettled conditions with possible periods of active conditions are expected later on April 2, due to the expected influence of the high-speed streams associated with the equatorial coronal hole (facing Earth on Mars 31).
