Bulletin

Solar activity is very low with no C-class or even B-class flares reported during last 24 hours. There are no active regions observed on the visible side of solar disc. We expect solar activity to remain low with possibly only occasional B-class flare. No Earth directed CMEs were observed in the last 24 hours.

The solar wind speed is about 350 km/s, and the interplanetary magnetic field magnitude is about 5 nT. The fast solar wind associated with the elongated equatorial coronal hole (between N10 to S25), which has crossed central meridian yesterday morning might arrive at the Earth in the morning of July 2 and induce unsettled to active geomagnetic conditions.

Today's estimated international sunspot number (ISN): 000, based on 18 stations.
