The comet 1P/Halley
From Fairfield , 1P/Halley is visible in the evening sky, becoming accessible around 18:47 (EST) as the dusk sky fades, 34° above your south-eastern horizon. It will then reach its highest point in the sky at 21:44, 50° above your southern horizon. It will continue to be observable until around 01:57, when it sinks below 22° above your 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 1P/Halley are available, however, and consequently the magnitude estimates shown here may be unreliable.
