Bulletin

The unnumbered region that developed yesterday to the south of NOAA 2664 produced an M1.3 flare peaking at 16:15 UT on July 3. This region is now behind the limb but still producing C-class flares, and can continue to do so in the next 24 h.

No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar protons have remained at background levels over the past 24 hours.

Solar wind speed is at 350 km/s with interplanetary magnetic field of 3 nT. Geomagnetic conditions are quiet and expected to remain so until the Earth is affected by the high speed stream from an equatorial coronal hole within 24 h. Active to minor storm conditions expected then.

Today's estimated international sunspot number (ISN): 000, based on 22 stations.
