Vadu Beach, Northern Dobruja, Romania
Vadu beach monolith, 3 faced, about 2.5-3m tall, clear signs of vehicle tires around at the time of finding. Clean sides, edges are riveted. One side contains symbols from the Predator lore (Yautja alphabet), translation is incomplete as not all symbols match: ? A 5 H 35M 17S ? 8(or 2) 3 8(or 2) 8(or 2).
Almost positive that those are Star Coordinates. That first symbol is most likely an "R" so the first two letters would be Right Ascension.
RA 05H24M17S then the 52328 are the degrees.
First symbols could suggest a time 5 hours, 35 minutes 17 seconds.
Also it's been cited that the symbols could be the coordinates for Orion Nebula.
Orion Nebula Coordinates: Right ascension: 05h 35m 17s. Declination:−05° 23′ 28″.
