DATE: 17 Feb 2020, composed at 08:38 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 320 - 355 km/s. Geomagnetic conditions are at quiet levels. Local HF working frequencies are near 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 on the visible Sun and no flaring activity is expected. The solar wind speed is expected to remain at background levels with a small chance of elevated winds due to influence from coronal holes 12 and 13 (CH12 and CH13). Geomagnetic conditions are expected to be mostly quiet with possibility of unsettled to active levels.

SYSTEMS AFFECTED: None.
