The solar activity was active with several C-class flares and one M-class flare recorded over the last 24 hours. The M1.5-class flare was observed on March 25 with a peak time at 05:25 UTC from the sunspot regions NOAA-AR 2974 located around latitude -19 degrees and longitude -38 degrees. This flare was associated with a radio burst emission of types II and IV, which indicate that a coronal mass ejection is associated with the flare event. For the next 24 hours, C-class flares are expected and possibly also M-class flare.

The Coronal Mass Ejection (CME) associated M1.5-class flare on March 25 around 05:25 UTC is associated with a very large coronal dimming (recorded by the Solar Demon Dimming Detection too) that reached the central meridian facing Earth. The main direction of the CME is South-East. However a possible Earth impact may be due to the arrival of the interplanetary CME western flank glancing on in about 3 days.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours and is expected to remain at nominal levels in the next 24 hours. The greater than 2 MeV electron flux remained below the 1000 pfu alert threshold and is expected to remain below the threshold in the next 24 hours. The greater than 2 MeV electron fluence dropped to nominal levels in the past 24 hours and is expected remained at nominal levels in the next 24 hours.

The solar wind parameters measured in the Earth environment (by DSCOVR) remained slightly enhanced under the influence of the effect from the solar high-speed stream connected to the Coronal Hole (positive magnetic polarity) that crossed the central meridian on March 20 (positive magnetic polarity). The solar wind speed was ranging from 575 km/s to 430 km/s, the interplanetary magnetic field remained close to 5 nT, and its southward Bz- component fluctuated between -3.6 nT and 4.1 nT. Then, the effect of the high-speed streams associated to a large equatorial coronal hole that faced Earth yesterday on March 24 (positive magnetic polarity) is expected to impact the solar wind conditions in about 1-2 days.

The geomagnetic conditions were quiet to unsettled levels (K-BEL and NOAA- Kp recorded values of 1-3). Geomagnetic conditions are expected to be quiet to unsettled then become more active with the arrival of the fast solar wind associated to the large equatorial coronal hole that faced Earth on March 24.
