Today's calendar reminder includes: > Nov 18 First hydrogen bomb blasts Enewetok, 1952
All the sources I could find online say that the first hydrogen bomb, the Ivy Mike device, was actually detonated on Nov 1 local (Oct 31 UTC). Wikipedia has a writeup https://en.wikipedia.org/wiki/Ivy_Mike Additionally, the common spelling of the atoll appears to be Enewetak (not -tok).
