The operator must know that Orión Group is near 180 sexagesimal degrees of the Scorpion Group. Or that when a group is a visible high in the sky, the other is "under our feet" or when one is in the East, the other is in the West Also the operator must know that: these constellation groups define epochs of the year
When in the south hemisphere is visible, high in the sky the Orion Group, beginning the night, is in full summer. If the Scorpion Gropu is high in the sky, beginning the night, is in full winter.
If to the beginning of the night, Orión Group is towards the West Horizon and Scorpion Groups towards the East Horizon, is an Autumn. If exactly to the inverse, will be spring.
For the Northern Hemispheres is exactly to the inverse of the Southern Hemisphere
We are saying very clair: Orion and Scorpius Groups are easiest constellations, between 88, that any person will identify. The remains are very difficult to identify without something of knowledge.
