Where possible, the brightnesses of comets are estimated from absolute magnitude values computed by the BAA Comet Section, based on the observations they receive. We prefer these to the Minor Planet Center's own magnitude estimates, since the latter are less often updated. Nonetheless, comets are intrinsically unpredictable objects, and magnitude estimates must always be taken with a pinch of salt.
