This book sets the scene for the arrival of Comet ISON and those comets following it over the next few years.
Sky watchers will have already been primed for C/2012 (ISON) earlier in 2013 with the apparition of another naked-eye comet, C/2011 L4 (PanSTARRS), and following C/2012 S1 (ISON) there is the prospect of 2012 K1 (PanSTARRS) reaching naked-eye visibility in August 2014. And there will be other bright cometary prospects in the near future, if we take into account the latest predictions.
The author explains how sky watchers and amateur astronomers can practically follow comets, observe them, and record them. This is also a guide on how to keep abreast of the latest cometary discoveries and how to use publications, websites, programs, and apps to visualize and plan observations.
