VIIRS Day-Night Band Imagery Shows Fire in VA Blue Ridge

On April 16th a fire was reported in the Shenandoah National Park in eastern Rockingham County, Virginia, situated roughly between the cities of Harrisonburg and Charlottesville. Estimated at about 500 acres (per latest news reports), the fire (named the Rocky Mountain Fire) is large enough and producing a sufficient amount of smoke to be seen in Geostationary satellite data from GOES-13 this afternoon (Image 1).

However, the fire can also be seen in Day-Night Band Imagery, produced by the VIIRS instrument aboard the Suomi-NPP satellite.  The first image below (image 2) shows no visible fire early on the morning of the 16th and the growth of the fire over the next couple of mornings in the next two images (images 3, 4).
