Mt. Etna, on Sicily in the Mediterranean Sea, erupted early in the morning on Nov 17th just before a Suomi/NPP overpass. The VIIRS Day/Night Band gives a clear view of the volcanic plume (and the light emitted by the lava in the caldera); thermal channels show a distinct hot spot: 360 K in the 11 micron channel, and 523 K in the 3.9 micron channel!
