Bülletään

Solar activity was at very low levels during the period. NOAA 2664 decayed further and was quiet. No earth-directed CMEs were observed in available coronagraphic imagery. The greater than 10MeV proton flux was at nominal levels.

Quiet flaring conditions are expected.

Solar wind speed gradually declined from 430 km/s to 340 km/s. Bz was relatively stable between -2 and +2 nT. The interplanetary magnetic field was mostly directed away from the Sun. The first of two small negative equatorial coronal holes (CH) is about to start transiting the central meridian.

The geomagnetic field was at quiet to unsettled levels, and is expected to remain so. A glancing blow from the 28 June CME is possible late on 2 or on 3 July, likely followed by the particle stream from the small negative CH. This may result in active geomagnetic conditions, with a chance on a minor storming episode.
