The comet 101P/Chernykh
From Seattle , 101P/Chernykh is visible in the evening sky, becoming accessible around 17:45 (PST) as the dusk sky fades, 27° above your south-eastern horizon. It will then reach its highest point in the sky at 19:53, 34° above your southern horizon. It will continue to be observable until around 22:48, when it sinks below 21° above your south-western horizon.

The Minor Planet Center's magnitude estimates are updated rather rarely, and so we prefer to estimate the brightness of comets on the basis of amateur observations. No amateur observations of 101P/Chernykh are available, however, and consequently the magnitude estimates shown here may be unreliable.
