In 1979, the International Astronomical Union's 17th general assembly recommended that newly discovered star clusters, open or globular, within the Galaxy have designations following the convention "Chhmm±ddd", always beginning with the prefix C, where h, m, and d represent the approximate coordinates of the cluster center in hours and minutes of right ascension, and degrees of declination, respectively, with leading zeros.
En 1979, a 17ª asemblea xeral da Unión Astronómica Internacional recomendou que os novos cúmulos, abertos ou globulares, que se descubran dentro da nosa galaxia sexan designados seguindo a convención "Chhmm±ddd", sempre empezando co prefixo C, onde h, m e d representan as coordenadas aproximadas do centro do cúmulo en horas e minutos de ascensión recta, e os graos de declinación, respectivamente, con ceros diante.
