Bulletin

Solar activity has been very low in the past 24 hours, with the strongest event being a C1 flare taking place in NOAA AR 2021, 1827UT (peak time) on April 5. NOAA AR 2026 and 2030, which were the main possible source of flaring activity yesterday show less magnetic complexity today. Eruptive conditions should prevail in the next 48 hours, with a slight risk of an isolated M class flare from AR 2030. Geomagnetic activity was unsettled to active in the past 24 hours, with a short period of indeed active conditions at planetary levels from 09 to 15 UT on April 5th, due to the arrival of the CMEs of April 1st and/or April 2nd.We expect mostly quiet conditions for the next 48 hours, with periods of unsettled conditions possible within the next 24 hours. Current ACE observations show the signature of a magnetic cloud, related to one of the aforementioned CMEs.

Today's estimated international sunspot number (ISN): 089, based on 13 stations.
