Bulletin

NOAA active region 2564 (Catania number 6) did produce two C-class flares, the strongest being a C8.6 flare peaking at 0:59UT. The flare was associated with a type II radio burst (observed at Learmonth) and a narrow CME, travelling away from the Sun-Earth line. No Earth directed CMEs were observed. More flaring at the C-level is expected from NOAA 2564.

The solar wind still is under the influence of the high speed stream, with solar wind speed values near 600 km/s and magnitude magnetic field of 5 nT. Quiet to unsettled geomagnetic conditions are noted, which are expected to mainly continue till a second enhancement of the solar wind starts caused by an expected coronal hole high speed stream at the end of July 11.

Today's estimated international sunspot number (ISN): 050, based on 20 stations.
