 Using dedicated as well as archival data obtained with //Herschel//, APEX, and ALMA, several transitions of AlO and AlOH were observed in the circumstellar shell of Mira. The AlO signals originate largely from the dust formation zone. Hence, AlO may well be (one of) the molecule(s) with which dust formation starts in O-rich AGB stars.\\ Using dedicated as well as archival data obtained with //Herschel//, APEX, and ALMA, several transitions of AlO and AlOH were observed in the circumstellar shell of Mira.
