As Dave kindly posted, Piuma fired against Ward, from his 5 or 6 o´clock, failing in the attempt. This is a great news as would be the only argentinean jet who get such a position against a Sea Harrier in all war.
Excuse me if I am wrong but in the 8 June fight didn't Hector Sanchez have a guns jam while flying behind Dave Morgan? He then overshot and escaped.
