ASASSN-14mv spectrum I noticed this page: http://www.spectro-aras.com/forum/viewtopic.php?f=6&t=1044&sid=9a04057e065b17e1fa3fec9775abce51 The spectrum apparently Halpha. The strongest signal appears to be He I 4471. The other lines are also similar to those of AM CVn. cf. http://adsabs.harvard.edu/abs/1975ApJ...200L..23R
