Solar activity was at very low levels in the past 24 hours. NOAA AR 2811 and 2812 produced only B-class flares. Solar activity is expected to remain at low levels.

No Earth directed CMEs were observed in the past 24 hours. A partial halo CME was visible early on March 26, but it was backsided, without consequences for the Earth.

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 mostly 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 speed varied between 420 km/s and 350 km/s in the last 24 hours. The interplanetary magnetic field magnitude varied between 4 nT and 7 nT, while Bz varied between -4 nT and 4 nT in the last 24 hours. The interplanetary magnetic field phi angle had a negative polarity (towards the Sun). The high speed solar wind associated with the coronal hole that crossed central meridian on March 24 is expected today. A transition to fast solar wind is expected in the next 24 hours.

Geomagnetic conditions were mostly quiet (Kp: 1-2 and K Dourbes: 1-3). The arrival of the high speed stream may increase the geomagnetic conditions to mostly active with isolated minor storm periods.
