Type IV radio emission detected at 02:56 UTC on September 30, 2026

A Type IV radio emission was detected on September 30, 2026, beginning at 02:56 UTC, according to an alert issued by the NOAA Space Weather Prediction Center (SWPC). The emission was observed by the PAL observatory and is associated with radio activity linked to solar phenomena.

Type IV radio emissions are continuous broadband emissions that typically follow the passage of solar flares or coronal mass ejections (CMEs). Such emissions often indicate the presence of energetic electrons moving in the aftermath of solar eruptions. According to NOAA’s Space Weather Scales, these events can sometimes be associated with large-scale solar disturbances, though this specific alert does not indicate immediate impacts for Earth.

Reviewing the solar events for the day, a B-class flare from active region 4535 (N11W45) began at 02:51 UTC, and the Type IV radio emission was detected shortly after. This close timing suggests a possible association between the flare activity and the observed radio emission.

The latest official forecast discussion indicated that overall solar activity remained at low levels, with no Earth-directed CMEs observed during the summary period. The geomagnetic field has been quiet and solar wind conditions have been ambient. Solar activity is expected to stay low, with only a slight chance of moderate flares through October 2. Forecasters note that an enhancement in solar wind is possible on October 2 due to a CME that departed the Sun on September 28.
