1930a

1930a is a designation that typically refers to a catalog number or identifier within a specific system, likely astronomical or scientific. Without further context, its exact meaning is ambiguous. In astronomy, catalog numbers are used to systematically list celestial objects. These catalogs can be for stars, galaxies, nebulae, or other astronomical phenomena. The "a" suffix often indicates a subdivision or a second cataloging pass within a larger system. For example, in some star catalogs, objects might be numbered sequentially, and if a new set of objects is discovered or reclassified, they might receive the same base number with an appended letter.

Similarly, in other scientific fields, "1930a" could be a laboratory sample identifier, a product code for a specific chemical compound, or a serial number for a piece of equipment. The year "1930" might suggest that the catalog or system originated around that time, or it could be an arbitrary part of the designation. The letter "a" often denotes a specific instance or variant within a set of items numbered 1930. Therefore, understanding the precise nature of "1930a" requires knowledge of the specific catalog or database from which it originates.
