Usage Notes or Etymology
This term is rooted in the Latin occultatio, derived from the verb occultare, meaning “to hide” or “to conceal”. Etymologically, it is closely linked to the Proto-Indo-European root kel, signifying to hide. In Indonesian, okultasi was absorbed through formal scientific terminology channels to precisely distinguish this celestial concealment phenomenon from other terms such as eclipse or transit. In social and scientific contexts, okultasi is used exclusively within formal astronomical discourse and space navigation. Its application emphasizes the perspective geometry between the observer, the foreground object, and the hidden background object. Pragmatically, this word provides a higher technical nuance than common words like covering, and is frequently found in observatory reports or research publications regarding the precision measurement of celestial diameters.
