Not sure how much this will help, but here's some discussion of the cometary terminology from Archaeoastronomy in East Asia (p. 6-8):
Laura said:Since two of the types of "guest stars" are supposed to be comets, and yet the Chinese had no problems at all designating comets and "bushy stars" and "broom stars" and "tailed stars" etc, so WHY that distinction?
Not sure how much this will help, but here's some discussion of the cometary terminology from Archaeoastronomy in East Asia (p. 6-8):
The technical terms for comet most commonly encountered in the records are kexing, "guest star" (anomalous astral body, either comet or nova); huixing, "broom star"; xingbo, "fuzzy star" (i.e. a tailless comet); and changxing, "long star," which are uniformly translated this way. In the past, some scholars have been perplexed by the compound xingbo, which appears to defy Chinese grammatical conventions by having xing "star/celestial body" modify bo "be fuzzy/bristle." However, bo has a verbal sense here, meaning "to become fuzzy or bushy." This is entirely consistent with cometary records where it is generally used to describe the appearance of tailless comets or the changed aspect of a comet that has grown a tail. This usage appears in some of the earliest records and probably derives from a conception in which stars were thought to be capable of spontaneously becoming fuzzy, growing a tail, and moving about. Rendering xing bo as "bushy star" by analogy with hui xing ("broom" plus "star"), which is quite properly translated "broom star", is misleading in that it obscures the possibility that bo may imply a change of appearance. Thus, when one reads in a record of the comet of 9 January 595,
14th year of the Kaihuang reign period of Emperor Wen of the Sui Dynasty, 11th month, day guiwei [20]; there was a broom star that became fuzzy in Xu [LM 11] and Wei [LM 12], and then reached Kui [LM 15] and Lou [LM 16]. (Sui shu: Tianwen zhi, ch. 21, 612)
One suspects that it is the comet's reappearance without a tail that is being reported in shorthand. Indeed, comparison with European reports of the behavior of this comet confirms this interpretation (Kronk, 1999).
[...] In the case of the cometary apparitions, although many have been published in the past, there are gaps in the record and a rigorous distinction has not always been made between comets and supernovae, the latter also often denoted by the term guest star.
