Aldebaran is heading for a heliacal rising as it transitions from left to right of the Sun or from an evening to morning appearance.
The distance from the observer to the horizon acts like a giant Sun visor so any star to the right of the Sun as it appears as a first dawn appearance is a property of the Earth's orbital motion just as Sirius provided the reference for the beginning of
a New Year in antiquity and the basis of the 365/366 day calendar cycle-
".. on account of the procession of the rising of Sirius by one day in the course of 4 years,.. therefore it shall be, that the year of 360 days and the 5 days added to their end, so one day shall be from this day after every 4 years added to the 5
epagomenae before the new year" Canopus Decree 238 BC
That is magnificent, exquisite and all those things that observers are supposed to admire with observations, interpretations and even practical purposes like timekeeping.
