Solar activity was at very low levels. Decaying sunspot group NOAA 2749 is barely visible and was quiet during the period. No earth-directed coronal mass ejections (CMEs) have been observed in available coronagraphic imagery. The greater than 10 MeV proton flux was at nominal values.

Solar activity is expected to remain at very low levels.

Solar wind speed remained enhanced, varying between mostly 450 and 520 km/s, and ending the period with values near 480 km/s (ACE). Bz ranged from -4 to + 2 nT, but was near 0 nT for most of the time. The interplanetary magnetic field (phi angle) was directed away from the Sun (positive sector). Quiet to unsettled geomagnetic conditions were recorded in both Kp and K Dourbes.

Geomagnetic activity is expected to be at quiet to unsettled levels until around 4 October, when the wind stream from a patchy negative polarity coronal hole in the southern solar hemisphere may exert some influence on the earth environment. Mostly unsettled conditions are expected then.
