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
