Solar activity was at very low levels during the period. NOAA 2664 was quiet. A filament eruption took place around 00:30UT just north of this active region. No earth-directed coronal mass ejections (CMEs) were observed in available coronagraphic imagery. The greater than 10MeV proton flux was at nominal levels.

Quiet flaring conditions are expected.

Solar wind near Earth was highly variable during the period, with a small shock observed at 16:27UT. Wind speed increased abruptly from about 365 km/s to 410 km/s, and total magnetic field strength Bt from 10.5 to 17 nT. The last 24 hours, solar wind speed ranged between 315 and 535 km/s, the maximum occurring around 04:55UT (DSCOVR). Bz ranged between -10 and +15 nT, being mostly positive except for a negative stretch between 04-07UT. The interplanetary magnetic field was mostly directed away from the Sun. The source of the solar wind variability is most likely a transient structure, with the impact from the 28 June CME still expected for later today or tomorrow 3 July. The trailing part of a negative equatorial coronal hole (CH) is transiting the central meridian.

The geomagnetic field was mostly quiet to unsettled, with active episodes at Dourbes during the 15-18UT and 06-09UT intervals. Kp was at minor storming during the 06-09UT interval, and at active levels from 09-12UT. 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 negative CH. This may result in further active geomagnetic conditions, with a chance on a minor storming episode.
