Dear All, The best, indeed only, period I find in Katsumi Haseda's data on V915 Sgr [vsnet-obs 27234] is 279 days which by chance phases nicely with the early photometry provided by Brian Skiff [vsnet-chat 2802]. Combining the two sets of observations gives a best period of 279.7 days with aliases at +/- 2... days, which is spot on the GCVS value of 281.8. It seems clear that the original classification of V915 Sgr as a Mira with this sort of period is right. If further observations from other monitoring programmes are published on VSnet then it will be a simple matter to provide a modern light curve and ephemeris for this, possibly, very consistent variable.
