Heard DX station at 5 degree elevation of ARISS with fixed Moxon Yagi!

There was a pass of International Space Station with just 10 degree maximum elevation along the Western side a few minutes back. Usually I do not hear anything on such passes, but decided to try my luck and pointed the Moxon Yagi towards the, North West, the direction of maximum elevation of the pass. Heard nothing at the time of closest approach (TCA). I was about to switch off the radio thinking that it was a lonely pass. I did not even hear the ARISS Morse Code beacon. It was then that I heard a DX station twice. Checked the elevation at that time on Argentinian Amsat satellite pass prediction page. It was just 5 degrees. Quite unusual for my limited setup! Space station was at a distance of 1800 km then.
