The comet 46P/Wirtanen
From Ashburn , 46P/Wirtanen is visible in the morning sky, becoming accessible around 01:27, when it rises to an altitude of 22° above your south-eastern horizon. It will then reach its highest point in the sky at 04:37, 38° above your southern horizon. It will be lost to dawn twilight around 05:53, 35° above your southern 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.
