Tiga kes ini bergantung kepada latitud pemerhati dan sudut istiwa jasad samawi:
The three cases are dependent on the observer's latitude and the declination of the [[celestial body]]:
 
*Objek berada di atas [[ufuk]] walaupun pada rembangan rendah; iaitu jika |sudut istiwa + latitud| > 90° (iaitu jika nilai mutlak sudut istiwa adalah lebih daripada kolatitud, di hemisfera yang sama)
*The object is above the [[horizon]] even at its lower culmination; i.e. if |declination + latitude| > 90° (i.e. if in [[absolute value]] the declination is more than the colatitude, in the corresponding hemisphere)
*Objek berada di bawah [[ufuk]] walaupun pada rembangan atas; iaitu jika |sudut istiwa − latitud| > 90° (iaitu jika nilai mutlak sudut istiwa adalah kurang daripada kolatitud, di hemisfera yang bertentangan)
*The object is below the horizon even at its upper culmination; i.e. if |declination − latitude| > 90° (i.e. if in absolute value the declination is more than the colatitude, in the opposite hemisphere)
*Rembangan atas adalah di atas dan rembangan rendah adalah di bawah ufuk, jadi jasad diperhatikan terbit dan terbenam setiap hari; dalam kes lain (iaitu jika dalam nilai mutlak sudut istiwa kolatitud daripada [[kolatitud]])
*The upper culmination is above and the lower below the horizon, so the body is observed to rise and set daily; in the other cases (i.e. if in absolute value the declination is less than the [[colatitude]])
 
The third case applies for objects in a part of the full sky equal to the [[cosine]] of the latitude (at the equator it applies for all objects, because the sky turns around the horizontal north-south line; at the poles it applies for none, because the sky turns around the vertical line). The first and second case each apply for half of the remaining sky.
