A thermal signature of the #BlueOrigin #NewGlenn #NG2 booster rocket was apparent in @NOAASatellites #GOESEast ABI spectral bands 8/9/10/16 (w/ a very subtle signature in Band 4) as it launched from @NASAKennedy in Florida. A signature of the rocket condensation cloud was seen in all 16 ABI Bands.

Now that #Melissa is behind us as a tropical system, we need to have an honest conversation about how the federal weather enterprise is still running because of volunteers & unpaid employees, and how this "shutdown" is not really a shutdown.

Federal weather enterprise rises to the occasion again with Melissa - thanks to volunteers and unpaid employees
When a federal government "shutdown" is not really a shutdown. And also looking at the continued longer term impacts of ongoing and threatened budget cuts.

After briefly intensifying to a Category 4 storm at 0300 UTC (between Jamaica and Cuba), Hurricane #Melissa later made landfall in Cuba as a Category 3 storm at 0710 UTC. The peak wind gust at Guantanamo (MUGM) was 75 kts (86 mph) at 0623 UTC.

The Advanced Dvorak Technique (ADT) satellite-derived intensity estimate peaked at 185 knots for #Melissa -- which, according to the developer at CIMSS, is the highest value to date for any tropical cyclone.

1-minute #GOES19/#GOESEast Visible images showed that soon after making landfall, the eye of Hurricane #Melissa became cloud-filled as the storm interacted with higher terrain on the western edge of Jamaica.

1-minute #GOES19/#GOESEast Visible and Infrared images with plots of GLM Flash Points showed prolific lightning activity within the inner eyewall of Category 5 Hurricane #Melissa as it approaches the SW coast of Jamaica. Low-altitude mesovortices persist within the eye.

Sunrise on Category 5 Hurricane #Melissa south of Jamaica -- 1-minute #GOES19/#GOESEast Visible and Infrared images showed a nice "stadium effect" with the eye, and GLM Flash Points highlighted abundant lightning activity within the inner eyewall.

1-minute Mesoscale Sector #GOES19/#GOESEast Infrared images + GLM Flash Points showed #Melissa as it intensified from a Tropical Storm to a Hurricane at 1800 UTC. Since that time, a large convective burst developed and wrapped around the eastern semicircle of the hurricane.

@daylightcounter.bsky.social you're on notice... theconversation.com/a-us-startup...
A US startup plans to deliver ‘sunlight on demand’ after dark. Can it work – and would we want it to?
Satellites beaming sunlight down to Earth sound like science fiction – and they have astronomers very worried.
