Simon-Diaz (IAC; La \nLaguna), A. de Burgos (NOT; La Laguna), report on behalf of a larger \ncollaboration:\n\nWe observed the faint transient AT 2019wxt (PS19hgw), spatially and \ntemporally consistent with the gravitational wave event S191213g (LIGO \nand Virgo collaboration, GCN 26402), with the Nordic Optical Telescope \n(NOT) equipped with the ALFOSC instrument. A spectrum with 2400 s \nexposure was secured starting on 2019 Dec 18 at 19:52 UT (MJD 58835.83), \ncovering the wavelength range 3200-9600 AA. Photometry yields i = 18.99 \n+/- 0.02 mag (AB) calibrated against the Pan-STARRS catalog.\n\nOur spectrum reveals a blue, mostly featureless continuum, which can be \nfit with a flat spectrum (F_nu propto nu^0). A narrow Halpha emission \nline is detected at z = 0.037, consistent with the catalogued value from \nNED, which we impute to emission from the underlying host galaxy. Our \nresults are consistent with the findings of Dutta et al. (GCN 26490).\n\nAt the present stage, the classification of this transient is unclear \nand we encourage further spectroscopic and photometric follow-up.",
