   Please follow this unabbreviated scheme.

   This practice of ten character limit (which appeared in a personal e-mail
discussion with George Djorgovski) was confused with a professional's
custom at least once, and was somehow exposed to J.G.

   Since it was already discussed shortly ago, I don't want to continue
the debate (and reappearance of a flood of JG postings here) but repeat
the essence.

   A quote from Djorgovski's words:

   It is clear that the CSS nomenclature (at least by its original intention)
refers to events rather than sources.  This probably explains Yamaoka-san's
attitude in [vsnet-outburst 10831].  The acronym "CSS" was already used
and we had to avoid using a (likely more authentic) abbreviation such as
CSS Jhhmmss+ddmmss.  It is a pity these CSS transients are not yet
incorporated into ADS/Simbad possibly due to the same reason or incompatibility
with the IAU naming scheme (we hope the GCVS team could resolve this
situation by assigning permanent GCVS names as early as possible).
