Stubbs (Harvard)\n\nFollowing the Pan-STARSS discovery (Smartt et al, GCN 18394) of candidates\nin the G184098 northern error region,  PESSTO, the Public ESO Spectroscopic\nSurvey for Transient Objects (see Smartt et al. 2015, A&A, 579,\n40 http://www.pessto.org), reports two further classifications.\n\nPS15cej is a type Ia supernova around maximum light (spectrum taken on\n2015-10-02) at z=0.049.\n\nPS15cel is a type II supernova, probably 2-3 weeks after maximum\nlight (spectrum taken on 2015-10-12) at z=0.05\n\nAll observations were performed on the ESO New Technology Telescope at\nLa Silla using EFOSC2 and Grism 13 (3985-9315A, 18A resolution).\nClassifications were done with SNID (Blondin &\nTonry, 2007, ApJ, 666, 1024). Classification spectra can be obtained\nfrom http://www.pessto.org (via WISeREP).\n\nEight optical transients have been detected to date (see GCN 18394, 18395).\nThe sky positions and G184098 localisation region is now visualised\non a plot on the GraceDB event webpage. Six have spectral\nclassifications, while the other two are most likely\nnow fainter than i ~ 21 mag.\n\nWe thank Leo Singer and Roy Henderson for assistance in clarifying the\ncontours, healpix interpretation and upload mechanisms.",
