Janzen, G. Hosseinzadeh, N. Meza, D. Mehta, A. Martas, B. Subrayan DLT40 SN Ia 1 DLT40 Matches a Type Ia via SNID (though one of the highest matches is at phase +12 days which is not consistent with the phase based on non-detection limits). A reliable classification was not obtained with GELATO. Presence of Ti trough suggests it is an underluminous SN Ia. Follow-up is encouraged. 2025TNSCR1186....1R

Andrew Howell (LCO/UCSB), Curtis McCully (LCO), Megan Newsome (LCO/UCSB), Estefania Padilla Gonzalez (LCO/UCSB), Joseph Farah (LCO/UCSB) Global SN Project SN II 0.007 1 Global SN Project The spectrum appears to be blue and almost featureless. A broad and shallow P-Cygni profile can be distinguished at around 6600 ang, and can be tentatively identified as Ha, although Hb cannot be clearly distinguished. Assuming the transient is associated with the nearby galaxy NGC 4192A, we adopt a redshift of 0.007. At this redshift, from the position of the minimum of Ha we measure an expansion velocity of ~13000 km/s. Therefore, we classify the object as a young type II SN. For reference, SNID (Blondin & Tonry 2007, ApJ, 666, 1024) finds some similarities with young IIb SNe. 2024TNSCR.828....1T

Andrew Howell, Curtis McCully, Estefania Padilla Gonzalez, Craig Pellegrino, Giacomo Terreran Global SN Project SN Ia 0.001183 1 1 Global SN Project Using 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

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

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

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.

Wiggins, Tooele, UT, USA, reports his discovery of a possible supernova (mag ~17.0) on an unfiltered CCD frame taken 2020 Feb 26 10:01:22 UT using a 0.35-m f/5.5 reflector near Erda, UT, USA. The new object is located at R.A. 20h37m10.72s, Decl. +66°06'12.80" (equinox 2000.0), about 22” SW of the center of NGC 6952. Wiggins notes that nothing was visible at this position on an image taken the day before, however the seeing then was very poor. 2020TNSTR.653....1W N

The velocity of the ejecta, as measured from SiII 635.5 nm, is around 13100 km/s, using the redshift of the host galaxy as reported by Haynes et al. 1997, AJ 113, 1197 (via NED). 2019TNSCR2772....1F
