The search starts at the `date` of this `Observer` and is limited to the single circuit of the sky, from antitransit to antitransit, that the `body` was in the middle of describing at that date and time. If the body did not, in fact, cross the horizon in the direction you are asking about during that particular circuit, then the search must raise a `CircumpolarError` exception like `NeverUpError` or `AlwaysUpError` instead of returning a date. )__doc__)methods rdescribe_riset_searchrs+ ~~  NN  N MrceZdZdZdgZej jZdZ e Z dZ dZ dZ ddZdd Zdd Zdd Zdd Zdd ZddZddZdZeddZeddZeddZeddZdZdZddZy)ObserveraMA location on earth for which positions are to be computed. An `Observer` instance allows you to compute the positions of celestial bodies as seen from a particular latitude and longitude on the Earth's surface. The constructor takes no parameters; instead, set its attributes once you have created it. Defaults: `date` - the moment the `Observer` is created `lat` - zero latitude `lon` - zero longitude `elevation` - 0 meters above sea level `horizon` - 0 degrees `epoch` - J2000 `temp` - 15 degrees Celsius `pressure` - 1010 mBar r c6|j}|j|_|j|_|j|_|j|_|j |_|j |_|j|_|j|_|Sr) __class__r,latlonelevhorizonepochtemppressure)selfos rcopyz Observer.copy.sk NN LL **]] rcdt|jdt|jd|jd|jd|j d|j d|jd|jd S) z8Return a useful textual representation of this Observer.z) strr,rrr elevationrrrrs r__repr__zObserver.__repr__<sI tyy>3tzz?88TXXt~~<<DMM ; .fUs7DI LL 6MO3dii?@FF Fr) isinstanceEarthSatellite TypeErrorr,rr$rXr+rr*r)r minute) rrstartsignr0rha ha_to_mover(resultrs `` ` @r_compute_transitzObserver._compute_transitKs dN +G   G  DI**  T _tyy (rkdUl3 z?T !J II U* *fQ1v:./ rNc*|j||ddS)8Find the previous passage of a body across the meridian.rrrrs r_previous_transitzObserver._previous_transitf$$T5#r::rc*|j||ddS)4Find the next passage of a body across the meridian.?rrrs r _next_transitzObserver._next_transitkrrc2|j||dtS)=Find the previous passage of a body across the anti-meridian.rrr rs r_previous_antitransitzObserver._previous_antitransitp$$T5#r::rc2|j||dtS)9Find the next passage of a body across the anti-meridian.rrrs r_next_antitransitzObserver._next_antitransiturrcP|j}|j||}||_|S)r)r,rrrr original_dater(s rprevious_transitzObserver.previous_transitz+  " "4 /! rcP|j}|j||}||_|S)r)r,rrs r next_transitzObserver.next_transits+   tU +! rcP|j}|j||}||_|S)r)r,rrs rprevious_antitransitzObserver.previous_antitransits+  & &tU 3! rcP|j}|j||}||_|S)r)r,rrs rnext_antitransitzObserver.next_antitransitrrct|j|z tk\rtd|d|jt|j|ztk\rt d|d|jy)aRaise an exception if the given declination is circumpolar.
