69632020-06-25 16:21:07Daniel PerleyDaniel Perley (LJMU)ZTFLBV0.00659ZTFThe continued up-and-down variability of this object over the last 200 days (as seen in ZTF alert photometry on public brokers), coupled with the relatively low luminosity (M_r ~ -14.3 at peak), suggests that this is more likely to be the sustained eruption of a luminous blue variable (LBV) and not a genuine supernova.2020TNSCR1936....1P
57372019-12-23 14:57:24Daniel PerleyD. Perley and K. Taggart (LJMU) on behalf of ZTFZTFSN IIn0.00659ZTFA 4x750s spectrum with SPRAT on the Liverpool Telescope shows a weak continuum with strong, intermediate-width emission lines of hydrogen (alpha, beta, gamma) and helium. The spectra show good consistency with previous type IIn supernovae (e.g. SN 1988Z), although the inferred luminosity is much lower than typical IIn SNe. The host galaxy is NGC 4045 (z=0.00659).2019TNSCR2684....1T
