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 has decreased with speeds between 400 - 440 km/s as the influence of a high speed stream from coronal hole 39 (CH39) continues to wane. Local geomagnetic conditions are at quiet levels. Local HF working frequencies are highly elevated compared to the monthly average predicted values.

OUTLOOK: Solar activity is expected to remain 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 continue to decrease with geomagnetic conditions expected to be at quiet levels. Another high speed stream from coronal hole 40 (CH40) is anticipated to reach Earth later on 14 to 15 November 2017. This brings a possibility of unsettled to active geomagnetic activity with periods of minor storm levels.
