Analysis of Solar Active Regions and Activity from 09/2100Z to 10/2100Z: Solar activity was very low. No flares were detected. The visible disk was spotless. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 09/2100Z to 10/2100Z: Geomagnetic field activity was at quiet levels. IIB. Geophysical Activity Forecast: Geomagnetic field activity is expected to be at quiet to unsettled levels during days 1 - 2 (11 - 12 October) due to weak recurrent coronal hole effects. Activity is expected to decrease to quiet levels on day 3 (13 October) as coronal hole effects subside. III.
