Andrew Howell (LCO/UCSB), Jamison Burke (LCO/UCSB), Craig\nPellegrino (LCO/UCSB) on behalf of the Las Cumbres GW Follow-up\nCollaboration\n\nWe detect a possible transient at RA Dec 217.28296 -38.190458,\n\nwhich we tentatively name ���Nemo���, on the outskirts of the galaxy 2MASX\nJ14290828-3811214 (redshift 0.07478 / distance 338 Mpc; Jones et al. 2009,\n���The 6dF Galaxy Survey Data Release 3,��� via NED).\n\n\nWe measure a preliminary aperture magnitude of 19.74 +- 0.12 in the i-band\n(but host contamination is likely) in a 300s image taken on 2019-04-26\n18:19:33 UT at a Las Cumbres SAAO 1m telescope. This corresponds to an\nabsolute magnitude of -17.9 at this distance. These values are corrected\nfor MW extinction (E(B-V) = 0.0874; Schlafly, E.F. & Finkbeiner, D.P.\n 2011, ApJ 737, 103).\n\n���Nemo��� is not visible in g-band images taken at the same time (2019-04-26\n18:13:52 UT) using a Las Cumbres SAAO 1m. The source does not appear in DSS\nred or blue images, though they are not as deep as our discovery image. The\ntransient is also not visible in images taken from the Las Cumbres\nObservatory 2m Faulkes telescope in the i band at 16:27:54, the r band at\n16:33:39 , and the g band at 16:39:24 (all on 2019-04-26; all times UT) but\nthese images are also shallower than the discovery image. Therefore the\ntransient nature of ���Nemo��� is not yet confirmed.",
