The Fast and Dark Side of Transients experiment (FDST; ATel #12362) reports the spectroscopic observation of SN 2019bie. The object was discovered by ATLAS survey, see Tonry et al. (2011, PASP, 123, 58) and Tonry et al. (ATel #8680). Classifications were done with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
The observations were performed on 2019-03-18 using SPRAT (Piascik et al 2014) on the Liverpool Telescope (Steele et al. 2004).
Survey Name | IAU Name | RA (J2000) | Dec (J2000) | Disc. Date | Source | Disc Mag | z | Type | Phase | Notes
ATLAS19dpw | SN2019bie | 14:42:38.020 | +56:08:10.24 | 20190228 | ATLAS | 18.3 | 0.117 | IIn | 2-3w | (1)
(1) The light-curve has a slow rise and the inferred magnitude of ~-20 makes it a luminous supernova, most likely a SN IIn due to its narrow emission Hydrogen lines.
