Thanks Steve and Shirley-- To add to the narrative Steve included, here is the account from the Official Navy bio on the ship:
".....entered Pearl Harbor on August 15, 1941 for defense patrol in Hawaiian waters and was in that port on December 7, 1941 when the Japanese launched their infamous aerial attack.
All its battle stations were manned at 8 a.m. and two minutes later its gunners were firing on enemy torpedo planes attacking battleship row. It assisted in destroying an enemy plane which crossed its bow about 200 yards ahead, then helped down another of a group of planes straffing battleship Nevada. About an hour later one of its boats, dispatched to the stricken battleship, Oklahoma, returned with two survivors of the battleship, having already landed twenty-five survivors in a place of safety in company with a motor boat from the battleship California. A rescue and breathing apparatus was sent to the California and Sacramento took aboard 36 survivors of Utah for subsistence along with one crewman of battleship Nevada. Sacramento earned one battle star for her actions that day."
Note that the above references guns in action at 0802.Also this should be taken in context with the account Steve provided where the veteran describes "what seemed like an hour"It should also be noted that SACRAMENTO was in a hard dock area with three other ships.Based on the descriptions I would say that it was one of the inboard pair and they were stem to stern against the dock and SACRAMENTO was the outboard ship with it's bow pointing roughly toward the ARIZONA, so that Battleship Row was on the port bow.This would allow all or most of the port side gun batteries some degree of safe fire zone.And the bow guns would have had a better--although restricted--sweep of the harbor as the attack approached Battleship row.

BTW--I made a significant error regarding the description of SACRAMENTO as a "boat". It was over 200 feet long and not your typical hoist-aboard boat....I had PT Boats on the brain and several of the early models were converted to "gunboats" in late 1943--particularly PT59 which became JFKs next command after he lost PT 109.
