In 1995 and 1996, Gray again searched for the signal using the Very Large Array, which is significantly more sensitive than Big Ear.  Gray and Simon Ellingsen later searched for and second occurrence of the signal in 1999 using the 26-meter radio telescope at the University of Tasmania's Mount Pleasant Radio Observatory. Six 14-hour observations were made at positions in the general point in the sky, but nothing like the Wow! signal was ever heard.
