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 low with background x-ray flux below B-class levels. Solar wind speed has increased with speeds between 450 - 500 km/s. Local geomagnetic conditions are at quiet to unsettled levels. Local HF working frequencies are highly elevated compared to the monthly average predicted values.

OUTLOOK: Solar activity is expected to be low with background x-ray flux below B-class levels. None of the the active regions visible on the Sun pose any threat for strong flares. Solar wind speed is still expected to keep increasing due to high solar wind speed stream from coronal hole 63 (CH63) during the next 24 hours. Geomagnetic conditions is expected to be unsettled to active levels during the next 24 hours. The solar wind speed should then start to wane later on 19th, which should then return geomagnetic conditions back to normal.
