  • Comet Lovejoy???s apparition has been so bizarre up to this point that it is difficult to anticipate just what might happen next ??? including the exact sort of tail it might unfurl in the morning sky.??? The visibility of the tail could improve in the days ahead as the comet moves away from the sun and the background sky darkens accordingly.
