Following several days of unrest, there was a moderate eruption of Volcán de Fuego in Guatemala beginning around 0630 UTC on 19 November 2018. GOES-16 (GOES-East) Upper-level (6.2 µm), Mid-level (6.9 µm) and Low-level (7.3 µm) Water Vapor images (above) displayed a signature of the volcanic plume, which drifted slowly northward and eastward for several hours. Since... Read More

An Antares rocket was launched from the NASA Wallops Flight Facility on the Eastern Shore of Virginia (Space.com article) at 0901 UTC (4:01 AM local time) on 17 November 2018. At 0902 UTC a subtle thermal signature was seen just southeast of the launch site on GOES-16 (GOES-East) Near-Infrared “Snow/Ice” (1.61 µm). Near-Infrared “Cloud... Read More

GOES-16 (GOES-East) Low-level (7.3 µm), Mid-level (6.9 µm) and Upper-level (6.2 µm) Water Vapor images (above) showed a large region of very dry air within a subtropical ridge over the central North Atlantic Ocean on 16 November 2018. Infrared brightness temperatures were unusually warm (brighter yellow to red enhancement) on all 3 Water Vapor bands,... Read More
