Daily Forecast

DATE: 09 Jun 2023, composed at 07:45 SAST

CURRENT CONDITIONS: Solar activity is low with background X-ray flux at lower C-class levels. A few C-class flares were observed during the last 24 hours. There are nine sunspot regions on the visible solar disk showing simple to complex magnetic configurations. The solar wind speed is at background levels with speed ranging between 300-365km/s. There are a few filaments on the visible disk that show minimal movement and will be monitored for any potential Earth-directed lift-offs. Geomagnetic conditions are at quiet levels. 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 lower C-class levels. There are nine sunspot regions on the visible solar disk showing simple to complex magnetic configurations. The probability for further C-class flaring is high, moderate for M-class and low for X-class. The solar wind speed is expected to increase slightly due to possible high speed-stream (HSS) effects from coronal hole 10 and 11 (CH10 & 11) during the next 24 hours. Geomagnetic conditions are then expected to be at quiet to unsettled levels, with a slight chance of active intervals.

SYSTEMS AFFECTED: HF Communications.
