Stubbs (Harvard)\n\nLipunov et al (GCN 24076) reported the discovery of an optical transient \nMASTER OT J140518.22-395309.9  close to the southern part of the \nskymap of LIGO/Virgo source S190408an. \n\nThe ATLAS survey (Tonry et al. 2018, Stalder et al. 2016) has detected\nthis source since MJD=58555 (2019-03-13) at  o = 17.4. It peaked around \nMJD=58569 at o = 17 and has a SN like lightcurve. There is no obvious\ncatalogued host galaxy. \n\nIn summary, we confirm the discovery of MASTER that this is a real \noptical transient (with no host galaxy) at coordinates : \n\n14:05:18.21 -39:53:10.0\n\n211.32588 -39.88612\n\nBut that it is almost certainly a foreground SN about 1 month old, \nand very unlikely to be related to LIGO/Virgo S190408an.",
