The comet 65P/Gunn
From Ashburn (click to change), 65P/Gunn is visible between 21:50 and 02:41. It will become accessible at around 21:50, when it rises 21° above your south-eastern horizon, and then reach its highest point in the sky at 00:18, 30° above your southern horizon. It will become inaccessible at around 02:41 when it sinks to 22° above your south-western horizon.

Magnitudes estimates are derived from observations sent into the BAA Comet Section, as compiled by Jonathan Shanklin and last updated on 1 August 2017. 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.
