The comet 47P/Ashbrook-Jackson
From Ashburn (click to change), 47P/Ashbrook-Jackson is visible in the evening sky, becoming accessible at around 17:58 (EST) as the dusk sky fades, 41° above your eastern horizon. It will then reach its highest point in the sky at 21:16, 68° above your southern horizon. It will continue to be observable until around 02:06, when it sinks to 24° 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 29 February 2012. 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.
