Kasliwal (Caltech), Yashvi Sharma (Caltech), Kishalay De (MIT), Anna Franckowiak (RUB)ZTFCV1ZTFThe spectrum shows a hot blue continuum with strong Balmer lines at an apparent redshift of zero, confirming a galactic origin for AT2021afpi. It also exhibits HeI and HeII emission lines. The spectrum resembles that of V2860 Ori, a classical nova of subclass He/N (De et al. 2021). Given this, and the rapid 10 magnitude brightening, AT2021afpi is likely a young He nova.2021TNSCR4053....1S

Pastorello (INAF-OAPd)Padova-AsiagoSN Ic-BL0.0073021Padova-AsiagoWe confirm the classification of R. Leadbeater. The spectrum resembles that of the broad line Type Ic SNe 2002ap and 1997ef about 10-15 days after light curve peak. A fairly good match is also obtained with that of a normal Type Ic event such as SN 2004ew (Taubenberger et al. 2006, MNRAS, 371, 1459) at a slightly earlier phase (3-5 days after maximum). We note that a prominent narrow interstellar Na I doublet is observed in absorption at the host galaxy redshift, with an EW = 3.6 A, suggesting significant line-of-sight reddening. The redshift of NGC 6798 is from Theureau et al. 1998, A&AS, 130, 333.2017TNSCR1557....1B

Pastorello (INAF OAPd)Padova-AsiagoSN I0.009346Padova-AsiagoThe spectrum shows several broad features reminiscent of the early spectra of Ic-BL supernovae.A broad absorption centred at about 591.0 nm (rest frame) can be identified with SiII 635.5 nm and then an expansion velocity of about 21000 km/s is estimated. However, this feature appears much stronger that in typical Ic spectrum and more consistent with the SiII feature in SN Ia. At this stage, the classification remains uncertain.2021TNSCR1031....1T

Andrew Howell, Curtis McCully, Estefania Padilla Gonzalez, Craig Pellegrino, Giacomo TerreranGlobal SN ProjectSN Ia0.0011831Global SN ProjectUsing Superfit (Howell et al. 2005, ApJ, 634, 1190) and SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find best fits to young SNe Ia, including a match to SN 2002bo 13 days before peak. The supernova is closest to SDSS J121551.28+130701.2 (z = 0.001183, 2016SDSSD.C...0000:, value from NED). Adopting this redshift we measure a Si II 6355 velocity of approximately 17,000 km/s. This velocity is consistent with an SN Ia approaching maximum light. Follow-up is encouraged. 2024TNSCR..44....1N

The possible supernova appears to be on the south-west of NGC 5363 and very close to the galaxy core. It's not shown up in WIKISKY or the Digitized Sky Survey. Estimated magnitude to be ~13.5 to 14.5 based on comparison to similar bright stars nearby. Reported by Philip Hoyle and assigned as AT 2020leu but seems with different RA/DEC coordinate. Just file this report as a supplemental documents.2020TNSTR1680....1Z
