Aguado (IAC and ULL), and A. López-Oramas (IAC and ULL) SGLF SLSN-I 0.2563 1 SGLF Classification performed using SNID (Blondin & Tonry 2007) with SN templates including SLSN Ic templates (Liu et al. 2017). The best match is for the type Ic SLSN SN 2011kg (PTF11rks) 9 days after maximum light. Redshift of z = 0.2563 from host-galaxy emission lines. At this redshift, the ZTF g-band peak magnitude after correction for interstellar absorption is of Mg = -21.7. We classify this transient as a SLSN Ic-BL. 2025TNSCR3129....1P
