Bulletin

The solar activity was very low since our last bulletin. No C-class flares were observed. NOAA active regions 2513, 2519 and 2521 (Catania 41, 44, 43) were stable, while Catania 42 and 45 were identified as two new sunspot regions (no NOAA number yet). Two filament eruptions occurred in the second half of March 13. The associated CMEs were rather narrow and not Earth-directed. No consequences for the Earth environment are expected. Flaring activity is expected to remain low, with some chance (30%) for C-flaring. Solar wind conditions are nominal with the magnetic field magnitude between 3 and 7 nT and solar wind speed ranging from 380 to 440 km/s. Geomagnetic conditions are quiet, both at global and local (Dourbes) level. Within the next 24 to 48 hours, the high speed stream from a negative polarity coronal hole might result in disturbances in the solar wind and increased geomagnetic activity (up to K=5).

Today's estimated international sunspot number (ISN): 059, based on 19 stations.
