DATE: 21 Jan 2020, composed at 08:30 SAST

CURRENT CONDITIONS: Solar activity is low with background X-ray flux below B-class levels. The solar wind speed is at background levels with speeds ranging between 280 km/s - 300 km/s. Geomagnetic conditions are at quiet levels. Local HF working frequencies are elevated compared to the monthly average predicted values.

EVENTS: None.

OUTLOOK: Solar activity is expected to be low with background X-ray flux below B-class levels. There are no sunspot regions visible on the Sun and no flaring activity is expected. The solar wind speed is expected to increase above background levels during the next 24 hours. A weak connection from coronal hole 03 (CH03) may slightly enhance the solar wind speed to 400 km/s on 21-22 January. Geomagnetic conditions are then expected to be mostly quiet with periods of isolated unsettled levels.

SYSTEMS AFFECTED: None.
