Bulletin

Solar activity remains to be at the low level, and there were no B-class or stronger flares reported during last 24 hours. The only numbered sunspot group on the visible side of the Sun, Catania sunspot group 88 (NOAA AR 2715), is rotating across the west solar limb which will result in even lower level of the flaring activity in the coming hours. No Earth directed CMEs were observed during last 24 hours, and the solar protons remained at the background level. The solar wind speed is still somewhat elevated and it presently amounts about 520 km/s. The interplanetary magnetic field magnitude is 5 nT. The fast solar wind associated with rather patchy equatorial coronal hole, which reached central meridian in the morning of June 27, might arrive to the Earth on June 30. The geomagnetic conditions remain to be quiet to unsettled and we expect they will not change in the coming hours.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 22 stations.
