Comet Pojmanski now has a turquoise tail several times longer than the full moon. The ion tail is due to gas particles expelled by the comet being pushed away from the Sun by the solar wind, the same wind that ionises gas in the tail causing its blue tint.

Comet Pojmanski has now begun to fade as its orbit around the Sun takes it further from the Earth.

On February 27th, sky watchers in the Northern Hemisphere will see the comet very low in the eastern sky about 90 minutes before sunrise. It will be roughly 7 degrees left, and below, the brightly shining planet Venus.
In binoculars or small telescopes the comet's "coma" should appear quite compact.
It may also display a short, faint narrow tail composed chiefly of ionised gases.

In the Southern Hemisphere, it is observable until early March. But it is only 15 degrees above the horizon. In the Northern Hemisphere, it will be observable after early March as a morning sky object.
