Daily Forecast

DATE: 27 Oct 2021, composed at 08:53 SAST

CURRENT CONDITIONS: Solar activity is moderate with background X-ray flux at upper B-class levels. Another M-class from a new active region (AR2891) has been observed at 15:42 UTC on 26 October and several C-class x-ray solar flares over the past 24 hours. The solar wind speed is slightly elevated above background levels with speed ranging between 320 - 415 km/s. This maybe due to weak influences from coronal hole features. Geomagnetic conditions are at quiet levels. Local HF working frequencies are near monthly average predicted values.

EVENTS: None.

OUTLOOK: Solar activity is expected to remain moderate with background X-ray flux at upper B-class levels. There are several active regions visible on the solar disk with AR2887 being the largest sunspot region and magnetically complex. The new active region (AR2891) produced two M-class flares on 26 October. A chance of further M-class and C-class flaring activity is expected from any of these regions. The solar wind speed is expected to remain slightly elevated above background levels possibly from weak influences of coronal hole features. Geomagnetic conditions are expected to be mostly quiet with isolated unsettled levels. The CME associated with an M1.3 solar flare is not Earth directed.

SYSTEMS AFFECTED: None.
