Calculate the time of next rise, set and transit for an object a body, usually Sun, a planet or Moon. E.g. it&#39;s sure, that rise, set and transit will be in &lt;JD, JD+1&gt; range.
Definition: rise_set.c:425

Calculate the time of next rise, set and transit for an object a body, usually Sun, a planet or Moon. E.g. it&#39;s sure, that rise, set and transit will be in &lt;JD, JD+day_limit&gt; range.
Definition: rise_set.c:455
ln_equ_posn
Equatorial Coordinates.

ln_get_object_next_rst
int LIBNOVA_EXPORT ln_get_object_next_rst(double JD, struct ln_lnlat_posn *observer, struct ln_equ_posn *object, struct ln_rst_time *rst)
Calculate the time of next rise, set and transit for an object not orbiting the Sun. E.g. it&#39;s sure, that rise, set and transit will be in &lt;JD, JD+1&gt; range. This function is not too precise, it&#39;s good to get general idea when object will rise.

int LIBNOVA_EXPORT ln_get_object_next_rst_horizon(double JD, struct ln_lnlat_posn *observer, struct ln_equ_posn *object, double horizon, struct ln_rst_time *rst)
Calculate the time of next rise, set and transit for an object not orbiting the Sun. E.g. it&#39;s sure, that rise, set and transit will be in &lt;JD, JD+1&gt; range.
Definition: rise_set.c:228
ln_lnlat_posn
Ecliptical (or celestial) Longitude and Latitude.
Definition: ln_types.h:200
ln_rst_time
Rise, Set and Transit times.
