Two days in a row of E6Bs launching from PAX RIVER to the GULF and
returning to PAX. Three days if 13 Aug is included.

The LANT E6B was active with multiple VLF broadcasts before it began it's
HF restoral/VLF sessions.

A very rare 17 character K7 prefix broadcast was correlated with TACAMO
LANT's activity over LANT.

Everything during the entire UTC day was probably related, IMO.

[Activity began either at 2100z or 2300z of UTC 15 Aug 26.]

[8 hour duration if it began at 2100z; 6 hour duration if it began at
2300z. 8 hours is similar to the 7 hour event of 27 Jun 2024 which included
a 51 character string at the at the 2nd broadcast (55 characters in today's
2130z second broadcast).]

Quiet.

[1348z: AE3524 E6B launched from PAX RIVER and flew to the GULF; eventually
returning to PAX. It made at least 3 circular orbits while over the GULF.
The VLF broadcast occurred while transitioning from the first circular
orbit to the 2nd.]

1404z: EASYWAY (presumed AE3524; launch call word; see 1800z for probable
secondary) called and raised MAINSAIL to enter the net.
1409z: EASYWAY entered the net.

[Strong suspicion this involves AFE627.]

[1456z: AFE627 E6B launched from PAX RIVER and flew to the ATLANTIC and
remained for 8 hours for many VLF broadcasts, one of which may have
involved a 17-character P2 EAM.]
