I watched 4 intensely glowing objects from a parking lot with 3 other witnesses.The objects were circular and had a dim dark colored outline, intensely glowing lights. The objects came from north-northeast and traveled southwest. They were a fire-like orange and flickered and pulsed like candles. Two of the objects were flying close together. The other three objects also were in the sky at the same time, but were spaced further apart.I heard a low hum which may or may not have been emanating from the objects, as we were next to a busy road.I am a student and musician, and the other witnesses were my elder brother who is an editor, close friend who is a programmer, and a cleaning lady who was passing by. We were all in awe, and the lady exclaimed that she believed them to be alien spacecraft.The objects did not appear to be planes, flares or drones. They resembled lanterns, but moved in the same way that a plane would, and looked much like burning meteors flying in sequence or formation.
