Oak - Hardtack 1
28/06/1958 - Barge shot - yield 8.9 Mt
Test of the LANL TX-46/53 device, Oak was one of the largest detonations at Enewetak Atoll. It exceeded it's predicted yield of 7.5 Mt, with the fission yield accounting for 5 Mt. The crater was 1.7km in diameter and 62m deep. This design was later developed into the 9 Mt W/Mk-53 warhead deployed on the Titan II missile and the Mk-53 strategic bomb.

Unidentified French shot from the 1970 testing year
My best guess is shot Licorne 03/07/1970 based on it's similarity compared to the other seven tests that year. If it is then it is from a completely different direction than the well known image of Licorne at roughly the same time. https://sonicbomb.com/v3.php?img=FR/img/licorne1.jpg

Bravo - Operation Castle
First image is 62 seconds after detonation, taken at a distance of 90 km north of ground zero at an altitude of 3000 meters. At this time the cloud is about 11 km in diameter. The second image is 16 minutes after detonation, where the cloud is in excess of 100 km wide.

Bhangmeter invention and deployment
Non-imaging radiometer devices know as Bhangmeters we dropped in cannisters from the instrument plane The Great Artiste during the atomic bombing of Hiroshima in 1945 to measure the yield. According to Wikipedia the Bhangmeter was invented and first proof tested in 1948 for Operation Sandstone. How can they have been used on 1945 when they were no invented until three years later?
