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 has increased slightly with speeds between 400 - 410 km/s due to the influence of a high speed stream from coronal hole 40 (CH40). Local geomagnetic conditions are at quiet levels. Local HF working frequencies are slightly depressed 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 is a new active region which emerged on the west-limb of the Sun but poses no threat for strong solar flare activity. The solar wind speed is expected to be elevated which could spark geomagnetic conditions to active levels. The high speed stream from coronal hole 40 (CH40) is expected to continue till late today. This brings a possibility of unsettled to active geomagnetic activity.
