Starbase 24

Memory Beta, the wiki for licensed Star Trek content.

Starbase 24 was a Starfleet facility in the 23rd and 24th centuries. It was the closest Federation base to the Klingon world of Khitomer. (ST novel: The Brave and the Bold)

The USS Enterprise had a layover at Starbase 24 circa stardate 3126.7, prior to its mission to Taygeta V. (TOS novel: The Tears of the Singers)

In 2346, a six-year old Klingon named Worf was treated at Starbase 24 for injuries sustained during a Romulan sneak attack on Khitomer. (TLE novel: The Art of the Impossible)

In 2376, Ambassadors Spock, Lwaxana Troi, and Worf all had stopovers at Starbase 24 prior to a diplomatic conference on Khitomer. (ST novel: The Brave and the Bold)

In February of 2381, during the invasion of the Borg Collective, a previously undetected Borg cube destroyed Starbase 24, along with the USS Merrimack, USS Ulysses, and USS Sparta. (ST - Destiny novel: Gods of Night)

In late April or early May of that year, Starbase 24, under the command of Commander Peter Abraham, relayed several reports from Klingon space, including news that Kinshaya ships using Breen disruptors had attacked the planet Krios. (ST novel: A Singular Destiny)

The apparent contradiction between Gods of Night and A Singular Destiny may indicate that Starbase 24 was able to be restored to at least partial operation shortly after the Borg assault. It's also possible the designation was reassigned to another facility in the interim.
