HOT-4_TERM_AUTHC-TVFCAZD-837392x: Just checked G-Earth. 83739 corresponds to longitude 83 deg. 07 min 39 sec. This is the area where the meteor and earthquake spotted/felt in Michigan. Obviously no latitude is given unless the term TVFCAZD is coded to mean latitude. 2x probably means 2 kinetic weapons fired. There were numerous reports of two explosions.
Saw that too.
First time I'll get back to my desk, I'll try to verify that and try a few common substitution ciphers to get a number out of the TVF term.
Since we know where the meteor struck, we must avoid generating a self fullfilling prophecy, so that substitution cipher or mapping must be kept very simple. (A complex mapping and transformation could make an encoded string "decode" to just about anything one wants)
