Re: Starfleet Command Insignia
If the above is true then since Commodore Wesley was wearing the star-burst/flower shaped insignia then he was probably considered starbase personnel that was temporarily in command of the USS Lexington.
That's the way I always took it. Plus, the Enterprise
picked up Wesley at a [originally unnamed] space station.
True, that unnamed space station
(which originally looked like the K-7 Space Station model) may have been considered a starbase too.
Excerpt below is from Memory-Alpha:
(Here is the link --> http://en.memory-alpha.org/wiki/Starbase
Starbases may be a deep space structure like K-7 or DS9, an orbital facility such as Starbase 1 (aka Earth Spacedock), a planetary surface facility, or a combination of both planetary surface and orbital structure(s) such as Starbase 11.
I don't know where Memory-Alpha got that information but I remember reading it somewhere years ago.
