The comet 185P/Petriew
From Ashburn , 185P/Petriew is visible in the morning sky, becoming accessible at around 23:45, when it rises 21° above your south-eastern horizon. It will then reach its highest point in the sky at 02:53, 37° above your southern horizon. It will be lost to dawn twilight at around 05:54, 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 2 April 2018. 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.
