Bulletin

The Sun produced five C class flares during the past 24 hours, with the strongest event being a C4 flare taking place in Catania sunspot group 8 (NOAA AR 2026) at a peak time of 6:31UT on April 7. Sunspot group 7 (NOAA AR 2031) emerged as a new and quickly evolving region and produced three of past C class flares. Eruptive conditions are expected in the next 48 hours, with a slight chance for an isolated M class flare. The magnitude of the interplanetary magnetic field is around 10 nT and solar wind speed near 400 km/s. Geomagnetic conditions were quiet to unsettled during the past 24 hours. We expect quiet conditions till the arrival of a shock related to the CME of April 4, around UT noon of April 8, possibly resulting in unsettled to active conditions.

Today's estimated international sunspot number (ISN): 083, based on 18 stations.
