A 10 cm radio burst associated with the solar flare was observed at 10:20 UT. This radio noise is generally short-lived but can cause interference for sensitive receivers including radar, GPS, and satellite communications.
A potential impact of the solar flare is a wide area blackout of HF (high frequency) radio communication for about an hour on large portions of the sunlit side of Earth, strongest at the sub-solar point. A radio blackout alert, scale: R3 – Strong, was issued by NOAA.
A Type II radio burst was also observed starting at 10:24 UT. Type II emissions occur in association with eruptions on the sun and typically indicate a coronal mass ejection is associated with a flare event. The estimated speed is 1049 km/s UT.
