Bulletin

The Sun released two C flares during the past 24 hours. The brightest flare was C3.0, peaked at 21:03 UT and was produced by NOAA AR 2320. It was associated to a dimming. In the next 24 hours, more C flaring is expected, with a slight chance for an M flare. The Earth is currently inside a solar wind flow with intermediate speed (around 450 to 610 km/s in the past 24 hours), with the magnitude of the Interplanetary Magnetic Field magnitude varying between 0.5 and 6 nT. The geomagnetic conditions are quiet (K < 4) and are expected to remain so on April 6 and 7. Late on April 7 or early on April 8, there is a chance for active conditions due to a possible glancing blow of the partial halo CME of April 4.

Today's estimated international sunspot number (ISN): 038, based on 09 stations.
