Magnitudes estimates are derived from observations sent into the BAA Comet Section, as compiled by Jonathan Shanklin and last updated on 29 February 2012. We use these amateur observations in preference to the MPC's magnitude estimates, since they are updated much more often. Nonetheless, all comets are intrinsically unpredictable objects, and future magnitude estimates must always be taken with a pinch of salt.
