A moderate solar flare reaching M1.6 was detected at 04:13 UTC around Sunspot 1560. The event was not long in duration and a large Coronal Mass Ejection (CME) is not expected.
Geophysical Activity Forecast: Geomagnetic field activity is expected to be at quiet to unsettled levels through the period (06 - 08 September) with a chance for active levels on day 1 due to possible weak coronal hole high-speed stream effects.
