Accepted Answer

Option A: At 0558, Mars can be used for an ex-meridian observation.. An ex-meridian observation requires the body to be near the observer's meridian. At civil twilight, planets near the meridian can be effectively observed using ex-meridian sight reduction techniques outlined in Bowditch and Pub 229.
