Typical sundials in the northern hemisphere have a style (also called gnomon, the thing that casts shadows) that points to the North Star, more precisely to the north celestial pole which is about 1° from the North Star.Jul 30, 2020

A horizontal sundial in the northern hemisphere has a gnomon that points north and the hour lines run clockwise. In the southern hemisphere, the horizontal dial's gnomon points south and the hour lines run counterclockwise. If you have an analemmatic sundial (horizontal but with a vertical human gnomon), then the date scale indicating where to stand is rotated 180 degrees when you change hemispheres - and the hour points progress clockwise in the north and counterclockwise in the south.

NOTE: Some resources on sundials may mention sundials showing shadows moving in a clockwise direction. This is only true for the Northern Hemisphere as shadow movement across sundials in the Southern Hemisphere is in an anti-clockwise direction.

There are many non NASA or any other sources noting observable differences in the Northern and Southern Hemisphere.
These, among others, are personal observations and constructs without previous input, instruction, or external determinations.
Sun Dials, and there orientations, are distinctly different in the Northern and Southern Hemisphere.
Star Fields as well.
Sun Dial - Terrestrial.
Star Field - Astronomical.
Both consistent with a Spherical (Geoidal) Earth.
NOT “flat” Earth.
”flat” Earth………
Stupid.
Stupid.
STUPID.
Without ANY doubt.
”flat” Earth.
