Two great circles, the solstitial colure and the equinoctial colure, intersect at the celestial poles. |

Lindley has made us acquainted with a species of Salix belonging to Senegal, and therefore to the equinoctial region of Africa. |
|
The Orinoco, the Eio Magdalena, and the Congo or Zaire, are the only great rivers of the equinoctial region of the globe. |
|
The declination of a heavenly body is its angular distance from the equinoctial or celestial equator. |
|
A star on the north side of the equinoctial is in northern declination, and one on the southern side is in southern declination. |
|
In Egypt generally, the solstitial worship followed that of the May and equinoctial years. |
|
The equinoctial colure is a great circle which passes through the celestial poles and the ecliptic at the two equinoxes. |
|
Consistently, equinoctial markers and alignments were made to an declination well over half a degree to the north. |
|
Two large stones also stand almost due east and west to mark the local equinoctial positions of the sun. |
|
One of the effects of equinoctial periods is their temporary disruptive effect on communications satellites. |
|
The sundial above, dated 1509, shows equinoctial hours with a gnomon parallel to the earth's axis. |
|
This colonizing plant grows mainly on the upper levels of salt marshes reached only by high equinoctial tides and storm waves. |
|
They are also equinoctial tides, occurring just after the autumn equinox on September 23, which would normally bring the highest tides of the year. |
|
Outside, the equinoctial storms of mid-September are raging. |
|
The temperature variation is pronounced, exceeding 23 ° C, and rainfall is primarily equinoctial. |
|
On nautical or professional equinoctial compasses for explorers, which have to be usable in the entire world, the latitude scale must be representative of any location on Earth. |
|
The science behind this is not fully understood, but the two equinoctial periods in spring and autumn tend to produce an increase in aurora compared with winter and summer. |
|
The equinoctial ring of the dial was hinged to the base plate and its gnomon was a narrow rod set at the centre of a pivoted bar lying across the West-East diameter of the hour ring. |
