Narrative:

My student was on his second supervised solo when he became part of an near midair collision. Left downwind abeam the tower, my student reported traffic in sight. (Later he said it was the wrong traffic.) he was cleared to land. As I watched him on short final, I noticed another aircraft somewhat near him. As I continued to watch, I noticed they were right on top of each other. Another instructor in the pattern advised the tower. Contacted tower, started to tell traffic to go around, but did not know what 2 aircraft were involved. My student had to make an immediate climbing left 90 degree turn to avoid traffic.
