It happened last night. I began shooting right at sunset, and that's when the lights started to come out. I believe I captured how they materialize at the beginning of the night. The large orb that appears in the sky stayed all night and is a UFO, kind of like the ring leader.

è la stessa cosa che filmo io spesso...se stasera arrivo presto a casa la posto..
Grazie
