According to the latest update, Comet Lovejoy will be a "no show" at magnitude 7, too dim to see with the eyes:


UPDATE: After four days of tracking, Comet Lovejoy's trajectory is known. The orbit is cockeyed, almost perpendicular to the rest of the solar system. At the moment the comet is swooping up from below, moving from southern to northern skies. At closest approach to Earth (0.44 AU) in late April, Comet Lovejoy is expected to brighten to 7th magnitude, still not a naked-eye comet but easy to see through small telescopes.
