HIMAWARI-8 thermal infrared satellite image collected on July 2, 2017 at 21:20 UTC (13:20 AKDT) of the volcanic cloud(red arrow) produced by the eruption of Bogoslof volcano. The explosive eruption began about 20 minutes prior to this image, and by this time the volcanic cloud had moved towards the east. A pilot report suggested that the cloud may have reached an altitude of 36,000 ft above sea level. The color scheme shows the temperature of the clouds in degrees Kelvin (Degrees Celsius+273). High clouds are cold (green-yellow-orange) and lower clouds are warm (blue-white).
