Bulletin

NOAA AR 1785 has increased significantly in size and number of spots. It has produced non-stop small scale flaring in the core of the active region. For these reasons, we expect up till M-class flaring in the next 48hr. We expect quiet geomagnetic conditions in the next 24 hours. The CME of July 1 is expected to miss the Earth and the coronal hole in the northern hemisphere is not expected to be geoeffective.

Today's estimated international sunspot number (ISN): 082, based on 12 stations.
