Solar activity was very low during the period, with no C-class flares or higher reported. The remnants of sunspot group NOAA2641 are barely visible. NOAA2638 rotated over the west limb. 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 to continue.

Earth was still under the influence of the high speed stream (HSS) from the negative trans-equatorial coronal hole (CH). Solar wind speed varied between 720 and 620 km/s, ending the period with values around 690 km/s. Bz mostly fluctuated between -5 nT and +6 nT. The interplanetary magnetic field was directed towards the Sun. A small positive equatorial coronal hole (CH) is near the central meridian, but the effect on the geo- environment is expected to be limited.

The geomagnetic field was at quiet to active levels, with Kp at minor storming during the 00-03UT and 03-06UT intervals. Quiet to active levels are expected, with a chance on another minor storming interval.
