The position of each comet is calculated from orbital elements published by the Minor Planet Center (MPC), and is typically known with a high degree of confidence.
Where possible, magnitudes are estimated from observations sent into the BAA Comet Section, as compiled by Jonathan Shanklin. We avoid using the MPC's own magnitude estimates, since they are rarely updated. Nonetheless, comets are intrinsically unpredictable objects, and magnitude estimates must always be taken with a pinch of salt.
