The comet 64P/Swift-Gehrels
From Ashburn , 64P/Swift-Gehrels is visible in the evening sky, becoming accessible at around 18:23 (EST) as the dusk sky fades, 68° above your south-eastern horizon. It will then reach its highest point in the sky at 19:48, 78° above your southern horizon. It will continue to be observable until around 01:24, when it sinks to 22° above your western horizon.

Magnitudes estimates are derived from observations sent into the BAA Comet Section, as compiled by Jonathan Shanklin and last updated on 2 January 2019. We use these amateur observations in preference to the MPC's magnitude estimates, since they are updated much more often. Nonetheless, all comets are intrinsically unpredictable objects, and future magnitude estimates must always be taken with a pinch of salt.
