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.
