Daily Forecast

DATE: 16 Feb 2018, composed at 08:45 SAST

CURRENT CONDITIONS: Solar activity is low with background X-ray flux below B-class levels. A glancing blow from a CME observed on 12th Feb has slightly increased the solar wind speed from 330 to 390 km/s. Local Geomagnetic conditions are at unsettled levels due to the CME influence. Local HF working frequencies are slightly elevated compared to monthly average predicted values.

EVENTS: None.

OUTLOOK: Solar activity is expected to be low with background X-ray flux below B-class levels. The one visible active region, 2699, has a simple magnetic configuration and no major flaring activity is expected. Solar wind speed is expected to further increase later today due to the connection of a high speed stream from coronal hole 67 (CH67). Geomagnetic conditions are expected to be unsettled to active with a chance of minor storm levels.

SYSTEMS AFFECTED: None.
