From Cambridge , 46P/Wirtanen is visible in the evening sky, becoming accessible at around 20:07 (EDT) as the dusk sky fades, 62° above your eastern horizon. It will then reach its highest point in the sky at 22:30, 85° above your southern horizon. It will continue to be observable until around 04:50, when it sinks to 21° above your north-western horizon.

Magnitudes estimates are derived from observations sent into the BAA Comet Section, as compiled by Jonathan Shanklin and last updated on 3 March 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.
