On 24 and 25 June the fire named 15BN-BRADY produced a pyroCb that was reported on (see blog post). On 26 June this fire produced another pyroCb at 22:00 UTC at 56.8 N 109.3 W. GOES-15 detected the smoke plume and pyroCb cloud, as well as the fire hot spot. Starting at 21:00 UTC on 26 June, the animation below shows visible (.63 μm) on the left and shortwave IR (3.9 μm) on the right (click image to play animation). In the shortwave IR images the red pixels indicate very hot IR brightness temperatures exhibited by the fire source region.Furthermore, using GOES-15 10.7 μm IR channel the cloud-top IR brightness temperature could be found. The animation below, starting at 21:00 UTC on 26 June, shows the brightness temperature of this pyroCb reaching -55.1ºC (yellow color enhancement) around 23:45 UTC.
