Il localise dans la partie sud de la constellation, dans une zone d\u00e9pourvue d’\u00e9toiles flashy et fortement obscurci; le meilleur moment pour votre observation dans le ciel du soir tombe entre les mois de Septembre et F\u00e9vrier et est grandement facilit\u00e9e par des observatoires dans les r\u00e9gions ‘h\u00e9misph\u00e8re nord terrestre, o\u00f9 il pr\u00e9sente circumpolaire<\/a>\u00a0jusqu’\u00e0 ce que les r\u00e9gions temp\u00e9r\u00e9es chaudes.<\/div>\n<\/div>\n<\/div>\n
