The comet 78P/Gehrels
From Ashburn , 78P/Gehrels is visible in the evening sky, becoming accessible around 20:41 (EDT) as the dusk sky fades, 60° above your southern horizon. It will then reach its highest point in the sky at 21:10, 61° above your southern horizon. It will continue to be observable until around 01:54, when it sinks below 22° 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.
