A meteor entered the Earth’s atmosphere over the Bering Sea (east of Kamchatka) on 18 December 2018. Himawari-8 “Red” Visible (0.64 µm) images (above) showed a bright streak at 23:50 UTC — and a dark-colored debris trail was also evident northwest of this bright streak, which subsequently drifted northeastward. Signatures of the meteor were also captured with the Terra satellite.

A warm thermal anomaly was apparent (at the southern end of the bright streak) on the 2350 UTC Himawari-8 Shortwave Infrared (3.9 µm) image (below).

GOES-17 was only scanning the Full Disk at 15-minute intervals, so the initial bright meteor streak that was seen with Himawari-8  was not not captured; however, the dark meteor debris cloud drifting northeastward could be followed on Visible imagery (below).
