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 CONDITIONS: Solar activity is low with background X-ray flux below B-class levels. Solar wind speed is at background levels with speeds between 380 - 460 km/s. Local geomagnetic conditions are at quiet to unsettled levels. Local HF working frequencies are slightly elevated compared to the monthly average predicted values.

OUTLOOK: Solar activity is expected to remain low with background X-ray flux below B-class levels. There are two simple active regions visible on the Sun with no flare activity expected. Solar wind speed is expected to gradually increase later today due to the expected arrival of a high speed stream from coronal hole 90 (CH90). Geomagnetic conditions are then expected to be at active to minor storm levels with a chance of moderate storm. HF propagation conditions may be disturbed.
