According to the JPL site, there was a bright meteor (or bolide) on September 29, 2021 over the Gulf of Alaska. (The JPL and a similar NASA site are posted under the GLM tab on this link of links.) This event was seen by both the ABI and GLM on NOAA‘s GOES-17, as well as the... Read More

The ABI on NOAA‘s GOES-17 (GOES-West) was able to see the Landsat 9 rocket plume from Vandenberg Space Force base. The plume was most evident on ABI bands 7 (3.9 µm) and 8 (6.2 µm), using the mesoscale sector (1) on September 27, 2021.The same animation as above, but as an animated gif. The 18:15 UTC image.

SSEC/CIMSS scientists (notably Rick Kohrs) create daily imagery that blends vertical strips of true-color imagery at local Noon, starting near the dateline and proceeding westward. A year-long animation of this product is available here, and was discussed on this blog previously here (and here). Recent images are available at this website... Read More

1-minute Mesoscale Domain Sector GOES-17 (GOES-West) “Red” Visible (0.64 µm), Shortwave Infrared (3.9 µm), “Clean” Infrared Window (10.35 µm) and Fire Temperature RGB images (above) revealed that the Cougar Peak Fire in southern Oregon produced a pair of pyrocumulonimbus (pyroCb) clouds— denoted by cloud-top 10.35 µm infrared brightness temperatures of -40ºC or colder (with the coldest being -64.9ºC at 0047 UTC) — late in the day...
