Type II radio emission detected at 06:50 UTC with estimated velocity of 671 km/s

A Type II solar radio emission was detected on August 14, 2026, beginning at 06:50 UTC. The estimated velocity of the associated coronal shock was 671 km/s, according to a Space Weather Prediction Center (SWPC) alert issued at 07:15 UTC.

Type II radio emissions are indicative of shock waves moving through the solar corona, often associated with the release of coronal mass ejections (CMEs). Such events can potentially be associated with solar energetic particle events and radio blackouts, depending on the strength and direction of the shock. According to the official alert, this event was categorized based on its velocity and radio emission characteristics; there is no confirmed Earth-directed CME at this time.

Review of solar event data for August 14, 2026, shows the Type II radio emission began at 06:50 UTC, which coincided with a solar flare (classified as SF) in Region 4503 observed at the same time and location (S18W57). This close timing suggests a possible association between the flare and the detected Type II radio emission.

Current solar activity is described as very low, with no Earth-directed CMEs observed in available coronagraph imagery. Isolated C-class flares remain likely, with only a slight chance for minor to moderate radio blackouts. Solar wind parameters are expected to increase under the influence of a positive polarity coronal hole high-speed stream, potentially leading to unsettled to active geomagnetic conditions through August 16, with a chance for minor geomagnetic storming.
