A large fire resulted from a train derailment in the town of Lac-M\u00e9gantic, Quebec at around 05:15 UTC (1:15 AM local time)<\/em> on 06 July 2013. According to the TSB investigation report<\/strong><\/a> and a CBC news story<\/strong><\/a>, the 72 rail cars were carrying crude oil. AWIPS images of 4-km resolution GOES-13 3.9 \u00b5m shortwave IR images (above; click image to play animation)<\/strong><\/em> revealed the fire “hot spot” (black to yellow to red pixels),<\/em> with a maximum IR brightness temperature value of 36.5\u00ba C on the 05:30 UTC image.<\/p>\n

The fire hot spot was no longer evident on the GOES-13 3.9 \u00b5m shortwave IR images after 06:15 UTC, perhaps because of partial obscuration by the approach of a patch of mid\/high altitude clouds from the west — however, a well-defined fire hot spot (with a maximum IR brightness temperature value of 54.5\u00ba C)<\/em> was still evident on a 375-meter resolution (mapped onto a 1-km AWIPS grid)<\/em> Suomi NPP VIIRS 3.74 \u00b5m shortwave IR image at 06:21 UTC (below)<\/strong><\/em>.<\/p>\n
