Bulletin

Solar activity remains to be low with no C-class flares reported during last 24 hours. There are no active regions observed, on the visible side of solar disc. Therefore, we expect solar activity to remain low. No Earth directed CMEs were observed in the last 24 hours. The solar wind speed is about 450 km/s, and the interplanetary magnetic field is stable with the magnitude of about 4 nT. The geomagnetic conditions are quiet and expected to remain so in the coming hours. In the late evening today, or in the morning of June 29, the fast solar wind associated with the elongated equatorial coronal hole which reached central meridian in the early morning of June 26, might arrive and induce unsettled to active geomagnetic conditions.

Today's estimated international sunspot number (ISN): 000, based on 19 stations.
