Daily Forecast

DATE: 28 Feb 2024, composed at 07:41 SAST

CURRENT CONDITIONS: Solar activity is low with the background X-ray flux at lower C-class levels. Several C-class flares were observed during the past 24 hours. There are six sunspot regions on the visible solar disk with simple to complex magnetic configurations. The solar wind speed is at background to slightly elevated levels with speed ranging between 380-450 km/s due to the waning effects of high-speed stream (HSS) effects from coronal hole (CH01/-). There are a few filaments on the visible solar disk that show slight movement and will be monitored for any Earth-directed lift-offs. Geomagnetic conditions were at quiet to unsettled levels with an isolated G1/minor storm interval. Local HF working frequencies are near monthly predicted values.

EVENTS: None.

OUTLOOK:  Solar activity is expected to be low to moderate with background X-ray flux at C-class levels. There are six sunspot regions on the visible solar disk with simple to complex magnetic configurations. The flaring probability for C-class is high, moderate for M-class and low for X-class. The solar wind speed is expected to be at background levels as the high-speed stream (HSS) from CH01/- wanes. Geomagnetic conditions are expected to be at quiet to unsettled levels.

SYSTEMS AFFECTED: HF Communications.
