Bulletin

Solar activity is low with no C-class flares reported during last 24 hours. Strongest reported flare was B5.8 flare which peaked at 09:58 UT today. We expect solar activity to remain low. The isolated low C-class flare is possible, although not very probable. No Earth directed CMEs were observed in the last 24 hours. The Earth is currently inside a slow solar wind flow with the speed of about 460 km/s. The interplanetary magnetic field is stable with the magnitude of 5 nT. The geomagnetic conditions are quiet and expected to remain so in the coming hours. The fast solar wind associated with the elongated equatorial coronal hole, which reached central meridian in the early morning of June 26, is expected to arrive in the late evening of June 28, and it might induce unsettled to active geomagnetic conditions. The ALL-QUIET-ALERT will be therefore canceled.

Today's estimated international sunspot number (ISN): 000, based on 14 stations.
