The moon in question was Jupiter VIII, now named Pasiphaë.

Some more Googling that I did led me to some more interesting information.

In fact, in my previous explorations, I had found that another of Jupiter's
moons was discovered in 1975, and then found again in 2000; but I didn't think
of it as a "lost moon" at the time, although it certainly was.

This satellite of Jupiter was S/1975 J1, temporarily known on its rediscovery
as S/2000 J1, and thus now established as Jupiter XVIII, or Themisto.

Dr. Scott B. Sheppard was is rediscoverer.

He also rediscovered S/2000 J11 after it got lost!

So there are three moons of Jupiter that could have been described as a lost
moon of Jupiter: Pasiphaë from 1941 to 1955, Themisto from 1975 to 2000, and
S/2000 J11 from 2000 to 2011.

And so Jupiter Jack, who has a radio show "Lost Moon Radio" on... oh, wait,
"Lost Moon Radio" is the name of a comedy ensemble. Based in Los Angeles. A
Google result I saw had me thinking it was a real-life radio show on a station
with the call letters KBBK.

The ensemble was founded in 2009, and during that time, S/2000 J11 really was a
lost moon of Jupiter.
