The IAU list of four-letter constellation
abbreviations
This is the International Astronomical
Union’s second list of constellation names with
alternative four-letter abbreviations, proposed and adopted at
the IAU’s 1932 General Assembly in Cambridge,
Massachusetts (Transactions of the
IAU, vol. 4, pp.221–2, 1933).
This list is unsatisfactory in several
ways. Firstly, there is a typo – the three-letter
abbreviation for Scorpius is wrongly given as “Scr”
rather than Sco. Then there are stylistic errors – there
should be no spaces in the three-letter abbreviations such as
“CVn”. Added to this is the confusing substitution
of Corona Austrina for Corona Australis. This list is best
forgotten, and was repealed by the IAU in 1955.
