 On October 7, 2015, Geoff Marcy posted an "Open Letter to the Astronomy Community" stating “While I do not agree with each complaint that was made, it is clear that my behavior was unwelcomed by some women.I take full responsibility and hold myself completely accountable for my actions and the impact they had.For that and to the women affected, I sincerely apologize.”

On October 12, 2015, the UC Berkeley Astronomy Department met and released a statement asserting that Marcy was "inadequately disciplined" by the University, and "we believe that Geoff Marcy cannot perform the functions of a faculty member."
