Bulletin

Solar activity was at very low levels during the period. NOAA 2664 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 parameters were at nominal values until around 18:00UT, when a gradual intensification set in. Bz had a negative stretch around -6 nT from 02:30UT till 05:30UT, then oscillated between -9 and +8 nT (DSCOVR). Wind speed was steady around 340 km/s till 08UT, before gradually increasing to values near 400 km/s. The interplanetary magnetic field was mostly directed away from the Sun. The first of two small negative equatorial coronal holes (CH) has transited 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.
