    Japanese Pronunciation of Comet Names

    The Computing Section introduces the following pronunciations for Comet Names. Japanese Pronunciations of Comet Names are written in Japanese. Also D. J. Asher has modified this list in 2012. Corrected Japanese Pronunciations of Comet Names(彗星名の正式表記) If your WebExplorer or Netscape has a multi-language option, please set it when reading this file.


    Observable Comets in Month

    The following Table contains Observable Comets in the Month, which are brighter than m1= 20.0 .OR. m2= 20.5 in the middle of month. Comet names are written in Japanese. The number of first columns are identical with those on the location in whole sky figure on the Temmon Guide (See p.176).
