B737 had a flap asymmetry condition on approach; crew performed a go-around and complied with procedure to uneventful landing. Flap asymmetry was a previously signed-off write up.

Narrative:
While reviewing the logbook; the captain and I both saw that there had been a trailing edge flap asymmetry on this aircraft recently. I believe it was the night before. It had been signed off by maintenance. We were flying a very normal visual approach at night in VMC backed up by the ILS. As we were completing the landing checklist; we noticed that although the flap handle was in the flaps 30 position. Both trailing edge flaps had stopped at about the flaps 1 position with one flap at slightly less than flaps 1. So; there was an asymmetry. We executed a normal go-around and were vectored to a crosswind and then a downwind by approach while we completed the QRH trailing edge flap asymmetry checklist. The subsequent landing and taxi in were uneventful. Crash fire rescue was requested as a precaution. We taxied clear of the runway to the pad. They inspected our aircraft and measured our brake temperature. After coordinating with maintenance; we determined we could safely taxi to the gate. I am unaware of any violations or other issues that occurred during this event.
