Was the Battle of the Barents Sea fought by day or night?

Was the Battle of the Barents Sea a day fight or a night fight?

It was fought during the Arctic winter, where near-continuous darkness at seventy-three degrees north made the ordinary day-night distinction much less useful.

The action took place on 31 December 1942 at approximately 73 degrees north and 29 degrees east. That position was well inside the Arctic Circle. The region's summer midnight sun has its winter counterpart in prolonged darkness, so nominal daytime did not mean ordinary daylight. The latitude and season therefore explain the conditions more clearly than a day-versus-night label.
