What is a .ast2 file?

The .ast2 file extension is associated with Astrologer, a specialized astrology software. These files store chart data, planetary positions, and astrological interpretations generated by the program. They are essentially personal records of astronomical alignments at specific times, used for birth chart readings and predictive astrology. Because they are plain text files, they are relatively simple and can be read with basic text editors, although they are primarily designed for use within the Astrologer application itself. This format aims to provide a structured way to save and recall complex astrological calculations and insights.
