The South African National Space Agency (SANSA) was established in 2010. Following a period of rapid growth and transition the agency has made significant advancements towards addressing its mandate of deriving greater value from space science and technology for the benefit of South African society.

CURRENT SPACE WEATHER CONDITIONS: Solar activity is very low with background X-ray flux below B-class levels. The solar wind speed is still elevated with speeds between 600 - 630 km/s as the influence of a high speed stream from coronal hole 39 (CH39) continues. Local geomagnetic conditions are mostly unsettled with periods of active storm levels. Local HF working frequencies are near to the monthly average predicted values.

OUTLOOK: Solar activity is expected to be low with background X-ray flux at lower B-class levels. There are no visible active regions on the Sun. The solar wind speed is expected to remain elevated during the next 24 hours before it starts to wane later on 11 November as coronal hole 39 (CH39) rotates of the visible side of the Sun. Geomagnetic conditions are expected to be mostly unsettled with periods of active levels. HF communications may be disturbed as the influence of CH39 high speed stream continues.
