We obtained 877 images of active asteroid 6478 Gault on 41 nights fromJanuary 10th to June 8th, 2019, using several telescopes. We created the phase,secular and rotational light curves of Gault, from which several physicalparameters can be derived. From the phase plot we find that no phase effect wasevident. This implies that an optically thick cloud of dust surrounded thenucleus hiding the surface. The secular light curve (SLC) shows several zonesof activity the origin of which is speculative. From the SLC plots a robustabsolute magnitude can be derived and we find mV(1,1,alpha) = 16.11+-0.05. Wealso found a rotational period Prot = 3.360+-0.005 h and show evidence that6478 might be a binary. The parameters of the pair are derived. Previous workshave concluded that 6478 is in a state of rotational disruption and the aboverotational period supports this result. Our conclusion is that 6478 Gault is asuffocated comet getting rid of its suffocation by expelling surface dust intospace using the centrifugal force. This is an evolutionary stage in thelifetime of some comets. Besides being a main belt comet (MBC) the object isclassified as a dormant Methuselah Lazarus comet.
