Bulletin

Flaring activity is expected to decrease as NOAA AR 1726 (Cat 51) is rotating further behind the limb. NOAA AR 1731 is relatively quiet up till now, despite a beta-gamma configuration. We are still inside a speed solar wind stream but most of the resulting geomagnetic activity is behind us. Quiet geomagnetic conditions are expected in the coming days.

Today's estimated international sunspot number (ISN): 075, based on 09 stations.
