1-minute Mesoscale Domain Sector GOES-17 (GOES-West) “Red” Visible (0.64 µm) images (above) showed the development of thunderstorms over the far southern end of the Alaska Panhandle on 27 June 2019. These storms intensified as they moved southeastward toward the Misty Fjords area of Alaska (located east and southeast of Ketchikan PAKT) — and when... Read More
The Ulawun volcano erupted just after 0430 UTC on 26 June 2019 — a comparison of Himawari-8 Visible (0.64 µm), Shortwave Infrared (3.9 µm) and Infrared Window (10.4 µm) images (above) showed the thermal anomaly (yellow to red 3.9 µm pixels) preceding the eruption and the development of a well-defined...

A SpaceX Falcon Heavy rocket launch of the STP-2 mission occurred at 0630 UTC (2:30 am EDT) on 25 June 2019. 16-panel images showing all GOES-16 ABI spectral bands (above) revealed visible and thermal signatures — ranging from hot thermal signals of air superheated by the rocket exhaust (perhaps best seen...

For the first time since 1924, a major eruption of the Raikoke volcano occurred around 1800 UTC on 21 June 2019. Himawari-8 False Color Red-Green-Blue (RGB) images from the NOAA/CIMSS Volcanic Cloud Monitoring site (above) showed — via the brighter yellow areas — that a large portion of the volcanic plume was rich...
