Pearson, N. Meza, D. Mehta, A. Ravi, A. Martas, B. Subrayan, L. Kwok DLT40 SN II 0.011 1 Add DLT40 We obtained a spectrum with Binospec on MMT on 2020-05-20 03:26:33 (MJD=60815.14). Based on narrow H alpha in the host spectrum, we find a redshift of 0.011 consistent with that of UGC 08255. Our spectrum shows a blue continuum with shallow P Cygni profile which peaks around 6630, corresponding to H alpha at the host redshift. We therefore classify AT2025ktz as a Type II supernova. Given the relatively deep non-detection, the supernova is likely young, however, the velocity is low (4000-5000 km/s) causing some degeneracy in the template matching. 2025TNSCR1856....1B

The slit in our observation was oriented to cover as well the bright galaxy 5.3” NW of this source. We detect several emission lines which we identify Halpha, Hbeta, [O III] and [O II] at a common redshift of z = 0.169. With a 15 kpc projected separation, this galaxy is thus a plausible host of AT 2025kmd/GOTO25cqo.

Andrew Howell, Curtis McCully Global SN Project SN Ia 0.0808 1 Global SN Project We report the classification of SN 2025jqj as SN Ia. The spectrum shows a best match to Ia norm SN 2007F from SNID (Blondin & Tonry 2007, ApJ, 666, 1024) 2 days before peak. The object redshift is acquired from the nearby host of WISEA J223815.48-245418.1 (z=0.080800, value from NED). Additional follow-up is encouraged. 2025TNSCR1733....1N

20978 2025-05-05 08:29:15 Panos Charalampopoulos Panos Charalampopoulos (UTU) None SN Ia 0.056 1 1 We report the classification of AT2025izo as a Ia supernova based on an optical spectrum obtained with the Nordic Optical Telescope on 2025-05-04 (i.e., MJD 60800.11). The transient is coincident with the nucleus of the host galaxy. Comparison with a library of supernovae spectra using SNID (Blondin & Tonry 2007, ApJ, 666, 1024), suggests AT2025izo is an around peak SN Ia at a redshift of z~0.056. We note that there is significant MW extinction (Av=0.535) making the ~ current absolute magnitude at that redshift be Mg = -19.2 (with an intrinsic g-r colour of ~ -0.25). 2025TNSCR1680....1C

O'Brien, G. Ramsay, K. Noysena, R. Kotak, R. Breton, L. Nuttall, E. Pallé, D. Pollacco, A. Kumar on behalf of GOTO collaboration GOTO SLSN-I 0.09 1 Add GOTO Spectrum is consistent with Type I SLSNe at redshift of about 0.09 to 0.1 (based on template matching). In the absence of any obvious host lines, we conservatively assume z=0.09. At the redshift the SN is brighter than -21.5 mag as expected for a SLSN. Further, the host galaxy appears to be a typical for SLSNe-I (i.e. blue and small) in Legacy Survey. As such, we classify the event as SLSN-I. 2025TNSCR1797....1P
