Being almost exactly on the celestial equator the star is visible everywhere in the world except for the North Pole.
There are two important planes in solar system calculations, the plane of the ecliptic(the Earth's orbit around the Sun),and the plane of the celestial equator the Earth's equator projected into space.
The celestial equator divides the celestial sphere into two halves: the northern and southern celestial hemispheres.
To define declination,the Earth's equator is projected out to the celestial sphere to construct the celestial equator, and declination is measured in degrees north or south of this celestial equator.
On 20 April 2013, Lemmon crossed the celestial equator and became primarily viewable in the Northern Hemisphere, though by this time the comet was significantly dimmer relative to its peak brightness.
Translated from Farsi, Navruz means"a new day"- the New Year on the solar calendar,which is when the sun crosses the celestial equator during the transition from the southern hemisphere to the northern one, that is, to the spring equinox.

The coordinates of objects on the sky are listed usingthe equatorial coordinate system, which is based on the projection of Earth's equator onto the celestial sphere.
The Babylonians used the concepts of the celestial sphere, the poles, the equator and the ecliptic.
On the celestial sphere, the second coordinate is the right ascension- an angle between the plane of a semicircle drawn from the celestial pole through a heavenly body(the hour circle) and the plane of a circle drawn from the celestial pole through the vernal equinox point on the equator the prime hour circle.
The wedge tilts the mount to an angle equal to the observer's Latitude, andtherefore it swivels around a plane which is parallel to the celestial(and Earth's) equator.
