Augustine volcano (Alaska): pilot reports large ash cloud, aviation color code raised to Red

Strong ash emissions from the volcano were reported by a pilot shortly after midnight (UTC). The reported height of the plume was to up to 70,000 ft (21 km) altitude, which would indicate an unexpected, and sudden major explosion took place (if the observed plume was volcanic ash and not something else). Anchorage VAAC raised the Aviation Color Code to RED.
No ash could be identified on satellite imagery, and the Alaska Volcano Observatory (AVO) has not issued any comment. In a subsequent VAAC, "ash emissions have ended", Anchorage wrote. It seems likely an unusual weather cloud had been mistaken for a volcanic plume.
