A slowly moving band of deep blue lights seen in the cloudless southern Tracy sky Monday night had a few people wondering Tuesday morning what the heck it was they saw. Larry Gustafson, 49, said his neighbor Ervin Floyd banged on his door at about 7 p.m. in the Morehead Park trailer court on Chrisman Road near 11th Street and urged him to check out the unusual sight. He said he ran outside, looked up, spotted the lights in the night sky and then ran back inside to grab binoculars. By the time he was back outside, the lights had disappeared. Gustafson said the lights hung in the sky about 5 minutes. Sometimes they moved, he said, and at other times, only one light shone. [ Visit Website ]
