This is a update of what I saw days ago..., I was looking for a familiar case and I founded one very very similar to what I saw on a mountain near my house. The case #18654, Ohio, Huber Heights, is exactly what I saw one night aprox. at 20:20 while I was walking my way home on August 1st, I saw a flash of bright green light, last aprox. 4 seconds and then vanishes, If someone can send me a e-mail with a logical explanation about this rare light phenomena please let him or let her know my e-mail. Thanks.
