Week-by-week ephemeris

Below is an ephemeris for C/2012 X1 (LINEAR), based on the latest orbital elements published by the Minor Planet Center (MPC) and updated daily. The future positions of comets are typically known with a high degree of confidence, but their brightnesses are often much more unpredictable, since it is impossible to predict with certainty how they will respond as they move closer to the Sun. Magnitude estimates should be assumed to be highly provisional more than a few weeks in advance.
