3356 2019-01-04 05:48:48 UCSCTr_Bot1 R. J. Foley (UCSC) None Other 0.001 1 The spectrum is blue with narrow Balmer emission. The H-alpha profile has a narrow (FWHM of ~250 km/s, consistent with the resolution of the spectrograph) and a broad (FWHM ~ 700 km/s) component. H beta, although noisy, appears to have a similarly broad (FWHM ~ 650 km/s) component. The difference-image flux is consistent with an absolute magnitude of -9.7 mag (neglecting any possible host-galaxy extinction). While some characteristics are consistent with a massive-star outburst, the luminosity is currently significantly lower than LBV giant eruptions. ATel: 12351 2019TNSCR..28....1F
