Bulletin
Solar activity is expected to reach eruptive levels with risks of C-class flares from NOAA ARs 1708 and 1710. A returning region, (previously AR 1698) is just beginning its transit on the disk, and might contribute as well to the slight increase in solar activity. Geomagnetic activity is expected to be mostly quiet for the next 48 hours, with periods of unsettled conditions. Minor storms conditions were observed on March 29 and from 00 to 06 UT on March 30. Strong excursions (down to -10 nT) of the Bz component of the interplanetary magnetic field were observed on March 29th, by the ACE spacecraft.
Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 052, sur la base de 08 stations.
