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 at lower B-class levels. Solar wind speed is enhanced with speeds between 500 - 600 km/s. Local geomagnetic conditions are at quiet to unsettled levels. Local HF working frequencies are slightly elevated compared to monthly average predicted values.

OUTLOOK: Solar activity is expected to be low to moderate with background X-ray flux at B-class levels. A chance of C-class X-ray solar flares is possible from active region 2651. Solar wind speed is expected to slowly decrease as the high speed stream from coronal hole 80 (CH80) wanes. Geomagnetic conditions are forecast to be mostly quiet to unsettled levels throughout today and tomorrow (21 - 22 April). Enhanced solar wind speed is expected again early on 23 April due to coronal hole 82 (CH82). Geomagnetic conditions are then expected to be at active to minor storm levels with intervals of moderate storm.
