The Minor Planet Center's magnitude estimates are updated rather rarely, and so we prefer to estimate the brightness of comets on the basis of amateur observations. No amateur observations of C/2010 U3 (Boattini) are available, however, and consequently the magnitude estimates shown here may be unreliable.
