Jennifer Andrews (U. Arizona), Stefano Valenti (UC Davis), Michael Lundquist (U. Arizona), Dave Sand (U. Arizona), Azalee Bostroem (UC Davis), Rachael Amaro (U. Arizona), Sam Wyatt (U. Arizona) report/s a classification of object: AT 2019qyl

Type: SN IIn
Redshift: 0.00048

Remarks: Using GELATO (Harutyunyan et al., 2008, A&A, 488, 383; gelato.tng.iac.es), we find the best fit to SN IIn/LBV. The SNIIn/LBV is likely in the host-galaxy NGC 300 (z = 0.00048; NED value). Taken at Gemini-S using GMOS. At the distance of NGC300 (distance modulus of 25.83; NED value) the object’s magnitude Mr=-8.5 is more consistent with an LBV (or very young SN IIn). An H-alpha P-cygni absorption was measured at 2000 km/s

The following Classification spectrum was provided:
