co-latitude
co-ˈlatitude Astron. [see co- 4.] The complement of the latitude, i.e. the difference between it and 90 degrees.1790 Roy Trigon. Operation in Phil. Trans. LXXX. 208 Its latitude will be 51° 6{p} 52{pp} 8; and hence PR the co-latitude will be 38° 53{p} 7{pp}.2. 1878 Lockyer Stargazing 329 The altitud...

Ionospheric dynamo region
In the auroral regions which lie between about 15° and 20° geomagnetic co-latitude and the corresponding latitudes in the southern hemisphere, precipitating Hough functions degenerate to spherical harmonics; e.g., mode (1, -2) develops to the spherical harmonic P11(θ), mode (2, 2) becomes P22(θ), with θ the co-latitude

How can I find the slope of a line tangent to a small circle on a sphere? I draw a circle on the earth, so that it passes through the north pole. I then begin walking around the circle, keeping track of my latitude. H...
one vertex on the North Pole, one vertex at the center of the drawn circle, and one vertex at your location
You know your latitude, so you know your co-latitude

Gyrocompass
In this case we have
With the next rotation (about the axis of an angle , the co-latitude) we bring the axis along the local zenith (-axis) of the barycenter As a side result, on measuring (and knowing ), one can deduce the local co-latitude

co-
co-, prefix of Latin origin. In Latin the preposition com- (which as a separate word was written in classical L. cum) was shortened to co- before vowels and h, also before gn-, e.g. coalescere, coercēre, coortus cohærēre, cognātus. Partly from the greater syllabic distinctness of this form of the pr...
