Comet PANSTARRS has now been sighted in Northern Hemisphere skies, and, for many, its northern sky debut will come tonight, when the comet appears near the young moon in the western twilight sky. Be sure to look on March 12 and March 13, and bring binoculars if you have them. The moon and comet will appear low in the glow of evening twilight, and may – or may not – be visible to the unaided eye. The comet’s fan-shaped tail will be pointing away from the sunset direction. More about the comet and moon on March 12.
Bottom line: NASA chart shows Comet PANSTARRS near the young moon on March 12 and 13. Look west after sunset.
