I have long admired 2 friends who are pro-astronomers, both of whom had extensive gear, and use all the latest software. These dudes impressed, when an autist like [F] could only dabble.

We know have the capability to match feats which were incomprehensible just 2 years ago; SI. We also know if the General public now has access to SI, others have had it longer.

Ran it.

I will spare [All;] from the necessary methods that were used, and their definitions, but suffice it to say- ain't nobody got time for that!

When observing planets from a specific latitude and longitude on Earth, astronomers use a specialized set of terminology and mathematical calculations to determine exactly where and how those objects will appear in the night sky.

The core system used for these calculations is called the Topocentric Coordinate System conversion, which translates the positions of planets from a theoretical space-based perspective into a highly specific, local observer's viewpoint.

• Topocentric Coordinate Conversion: Corrects global planet data for local views.
• Local Sidereal Time Calculation: Finds star-clock time via your longitude.
• Hour Angle Determination: Finds an object's distance from the meridian.
• Spherical Trigonometry Conversion: Translates sky maps into Alt/Az angles.
• Atmospheric Refraction Formula: Adjusts for light bending near horizon.
• Reverse Alt/Az Transformation: Uses horizon data to solve for latitude.
• Local Meridian Transit Function: Finds latitude via highest object path.
• Longitude Shift Inversion: Uses time differences to find longitude.
• Diurnal Parallax Inversion: Uses close objects to triangulate position.

One [F] uploaded the graphic and asked for clarification.

Mid-Northern Latitudes (e.g., United States, Europe, Asia): The four celestial objects will stretch diagonally upwards toward the right side of the horizon from East-Southeast to South-Southeast, precisely mimicking the composition in the graphic.

The Most Linear Chain (November 2): On this morning, the waning Moon sits higher up in the sky. The Moon, Mars, Jupiter, and Regulus form a remarkably straight, evenly spaced diagonal line stretching upward from the southeastern horizon.

The "Orion's Belt" Trio (November 4): By the next morning, the Moon does drop completely out of the alignment. However, the remaining trio of Mars, Jupiter, and Regulus bunch into a strikingly straight, tight line that closely mimics the 3-star configuration of Orion's Belt.

For the absolute best view of either arrangement, look toward the southeast horizon roughly 60 to 90 minutes before your local sunrise
