Luoxia Hong (140-87 BC) was the most famous folk astronomer in ancient China. He performed accurate observations with instruments (e.g., the equatorial armillary sphere) he made himself. He also produced Tai Chu Calendar, the first mathematical astronomy system in China, the standard for two millennia.Naming citation (20040713/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
