I've created an animation of Comet Lovejoy consisting of three images taken on consecutive days at approximately the same time. Each image is a crop from a singe photo taken using the same settings. Pay attention to the motion of the comet and how the brightness decreases over the three day period. I fear Comet Lovejoy might quickly become too dim to see with the naked eye.
If you live in the Southern Hemisphere you really need to do yourself a favor and make some time to observe the comet while you still can!
