Bulletin

The Sun produced just a handful of low C flares over the past 24 hours, the strongest occurred in NOAA AR 2026 peaking at C3.6 level at 14:15 UT, March 31 and another C3.3 flare originated from NOAA AR 2022, peaking at 00:50 UT, April 1. Solar flaring activity is expected to remain at C level with only a small probability for M level flares. The solar wind speed is steady at around 400 km/s with the magnetic field just slightly higher than yesterday: between 4 nT and 7 nT. Geomagnetic activity was unsettled in the second half of March 31 later returning to quiet despite the anticipated arrival of the March 28 CMEs. Local K Dourbes is presently rising from quiet to unsettled levels. The coronal hole that passed the central meridian on March 28 may become geoeffective and further unsettled conditions to minor storm levels are expected when/if the CMEs of March 28 and March 29 arrive.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 073, sur la base de 19 stations.
