FY-2D 0.73 \u00b5m Visible image<\/p><\/div>\n

A Meteor entered the Earth’s atmosphere over the Ural Mountains of western Russia today at approximately 0320 UTC (09:20 AM local time). The visible image from just after sunrise, above, from the Chinese FY-2D satellite shows an east-west plume, likely from the meteor, near Chelyabinsk. Meteosat-9 also captured the event (YouTube<\/a> | EUMETSAT<\/a>), as did Meteosat-10<\/a>.<\/p>\n

FY-2D has multiple channels. An animation of the visible (0.73 \u00b5m)<\/a>, near-infrared (3.8 \u00b5m)<\/a>, ‘water vapor’ (6.8 \u00b5m)<\/a> and far-infrared (11.0 \u00b5m)<\/a> is shown above. The signature of the meteor vapor trail is present in each of the channels. A before\/after comparison (03:00 and 03:30 UTC) of FY-2D 0.73 \u00b5m visible, 3.8 \u00b5m shortwave IR, 6.8 \u00b5m water vapor, and 10.8 \u00b5m IR window channel images is shown below.<\/p>\n

\"Before\/after<\/a>

An oblique view using Visible (0.73 \u00b5m) images from the Japanese MTSAT-2 satellite (below)<\/em><\/strong> revealed that the stratospheric component of the meteor vapor trail could be seen for as long as 9 hours with the aid of illumination from the sun.<\/p>\n

Since the vapor trail was not a particularly dense cloud, it did not exhibit a distinct signature on the Infrared Window images; however, there was still a faint thermal signal due to the fact that the mean meteor trail infrared brightness temperature of around 242 K (-31 \u00baC) was significantly warmer than that of the background infrared brightness temperature of space (165 K or -108 \u00baC).<\/p>\n
