The comet 48P/Johnson
From Fairfield , 48P/Johnson is visible between 19:27 and 05:37. It will become accessible around 19:27, when it rises to an altitude of 21° above your eastern horizon. It will reach its highest point in the sky at 00:34, 66° above your southern horizon. It will become inaccessible around 05:37 when it sinks below 21° above your western horizon.

Where possible, the brightnesses of comets are estimated from absolute magnitude values computed by the BAA Comet Section, based on the observations they receive. We prefer these to the Minor Planet Center's own magnitude estimates, since the latter are less often updated. Nonetheless, comets are intrinsically unpredictable objects, and magnitude estimates must always be taken with a pinch of salt.
