Solar activity is low and there were no B-class or stronger flares reported during last 24 hours. Since there is presently only one active region observed on the visible side of the solar disc, Catania sunspot group 88 (NOAA AR 2715), we expect low flaring activity to persist in the coming hours. Coronagraph images do not show signatures of the Earth directed CMEs, and the solar protons remained at the background level. As expected, the solar wind speed increased this morning and it presently amounts about 560 km/s. The interplanetary magnetic field showed smooth increase, observed starting from midday of June 25, which was followed by strong variation of its Bz component. All this, together with the observed sector change, indicates arrival of the fast solar wind associated with the recurrent coronal hole (the low latitude extent of the southern polar coronal hole which is reaching even up to the solar equator). Due to the longer interval of negative value of the Bz component, both local station at Dourbes and also NOAA reported disturbed geomagnetic conditions (K=5 and Kp=5, respectively). The geomagnetic conditions are presently unsettled to active and we expect such geomagnetic conditions to persist in the coming hours.
Today's estimated international sunspot number (ISN): 015, based on 25 stations.
