Campillay (LCO) None LBV 0.001558 1 The spectrum is blue with Balmer and He I P-Cygni features and several strong absorption features including Ca H&K and several Fe II lines. The spectrum is generically similar to 'cool' LBV outbursts such as UGC 2773 OT-1 (Smith et al., 2010, AJ, 193, 1451; Foley et al., 2011, ApJ, 732, 32). The spectrum is also similar to the Type IIn SN 1994W (Sollerman et al., 1998, ApJ, 493, 933). Correcting for the small redshift of NGC 0045 (cz = 467 km/s; Monnier Ragaigne et al., 2003, A&A, 408, 465), we find that the minimum of the H-alpha absorption for AT 2018htr is blueshifted by -1240 km/s. The absorption feature extends to approximately -2100 km/s. ATel: 12166 2018TNSCR1692....1S
