UFO Sighting in Los Angeles, California on December 10th 2012 – object appeared,, hover, then start moving in eratic way, then disappear,, then reappear and repeated….

was waiting for the bus when i noticed a strange object above me and my wife. flew near cloud level altitude,, appearing star like, solid in color, orange, red, and white...Flying South, coming from nearby mountains.. flew straight south, sometimes zig zaging, then would stop and hover, while moving side to side, up and down, very quickly. Made no sound whatsoever, and had pulsating lights that were probably going all around the object, appearing boomerang shape after... after hovering for few minutes, disappeared going straight up.. in a blink of an eye... when i thought it was over,, object reappeared,, coming the same way it did before,, did same manauvers,, and was gone... there were helicopters moving toward the object,, maybe they saw it too, and a cesna kept circleling at higher elevation around the object at higher altitude.... clearly wasnt a helicopter nor plane...... took pictures of object which were not altered..... and keeping in mind drones were not common as they are now....
