From Fairfield , 289P/Blanpain is visible in the evening sky, becoming accessible around 17:40 (EST) as the dusk sky fades, 26° above your southern horizon. It will then reach its highest point in the sky at 18:22, 27° above your southern horizon. It will continue to be observable until around 20:22, when it sinks below 22° 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 289P/Blanpain are available, however, and consequently the magnitude estimates shown here may be unreliable.
