DATE: 27 May 2022, composed at 08:29 SAST

CURRENT CONDITIONS: Solar activity is low with background X-ray flux at upper B-class levels. There were occasional C-class flares observed from visible active regions. There are seven sunspot regions visible on the solar disk. The solar wind speed is near background levels with speed of 300 km/s. Geomagnetic activity is 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 at upper B-class levels. There are seven sunspot regions visible on the solar disk with simple to complex magnetic configurations. The probability for C-class flaring is high, moderate for M-class, and very low for X-class. Solar wind will increase later today due to the arrival of the fast wind of coronal hole 84 (CH84). Geomagnetic activity is expected to be at quiet levels.

SYSTEMS AFFECTED: None.
