Two sunspot groups presently observed on the visible side of the solar disc, Catania 32 and 33 (NOAA AR 2662 and 2663) are showing signs of decay. Solar flaring activity is low with only one B-class flare reported during last 24 hours. The B1.4 flare which originated from the Catania sunspot group 33 (NOAA AR 2663) peaked at 02:57 this morning. We might expect only isolated B-class flares in the coming hours. All the observed CMEs, during the last 24 hours, were narrow and will not arrive to the Earth.
The solar wind speed is presently 440 km/s, and the interplanetary magnetic field magnitude is 6nT. The fast solar wind associated with two large coronal holes (one on the north and one on the south solar hemisphere) which reached central meridian in the evening of June 14 is expected to arrive at the Earth in the morning of June 18, inducing active to minor storm geomagnetic conditions. Geomagnetic conditions are presently unsettled to active and we expect them to stay so in the coming hours. During June 18, active to minor storm conditions are expected.
Today's estimated international sunspot number (ISN): 032, based on 20 stations.
