Dates Of Last Observation Of Comets
The following tables list the date of the last confirmed astrometric observation reported to the Minor Planet Center (MPC) for each of the currently-observable comets. It is hoped that these tables will assist observers in planning a useful program of astrometric observation of these objects.Observers are reminded of the efficiency of making and reporting observations of specific objects on pairs of nearby nights, as the accuracy of an isolated single-night observation can be difficult to judge.
