Srinath flew solo around the Livermore traffic pattern. Just as he turned downwind on one of the patterns, tower cleared him as #2 for 25L and Srinath confirmed he was scanning for traffic (3BE) that was on a 3 mile final. But it was clear he never saw the traffic. He was on base when he asked if he was #1 for 25L and tower reminded him he was #2 behind the traffic which was now on a short final. It turned out that Srinath turned too soon so there wasn’t enough separation with the traffic ahead that had just landed and hadn’t yet turned off the runway. Tower asked Srinath to go around, after which he did a couple more patterns before calling it a day.
