NAZA announced Green Comet Timings to See in USA discovered by Earth for the first time.

As the comet nears Earth, observers will be able to spot it as a faint green smudge near the bright star Polaris, also called the North Star. Comets reflect different colors of light due to their current positions in orbit and chemical compositions.

Early morning skies, once the moon has set after midnight for those in the Northern Hemisphere, are optimal for viewing the comet. The space object will be more difficult to see for those in the Southern Hemisphere.

What is ‘the green comet’ and how can you see it?
C/2022 E3 (ZTF) was last visible during the stone age so if you miss it this time you’re unlikely to get another chance
passing by Earth, the comet will make its closest approach of Mars on February 10, according to EarthSky.
Depending on its brightness, C/2022 E3 (ZTF) may even be visible to the unaided eye in dark skies, but binoculars or a telescope will make the comet easier to see.
