Narrative:
Red nose gear unsafe light came on in cruise flight. Performed communication procedures. Did not fix situation. Diverted to atl. Landed without incident. Callback conversation with reporter revealed the following information: the first officer was flying a DC9-50 in cruise flight when the nose gear unsafe light came on. He went through the procedure in the abnormal checklist and was unable to correct the problem. The flight crew contacted their maintenance control center, and after attempting to correct the situation using several techniques suggested over the radio, they decided to divert to atl and have their maintenance facility there correct the problem. They were less than 100 NM north of atl at the time. The reporter said that he did not know exactly what the technicians did, but he suspects that a limit switch was adjusted and the gear mechanism was cleaned. The delay in atl was minimal and they departed for their destination.
