In ATel#16478, we incorrectly listed AT2024atp for the classification of AT2024ats. We provide the corrected text below and apologize for the mistake.
We report the following the classifications of astrophysical transients from spectroscopic observations with the LRIS spectrograph on the Keck I telescope, made on 2024 Feb 14 UT. The targets were supplied by YSE and ATLAS, and identified using the target management platform YSE-PZ (Coulter et al., 2023, PASP, 135, 4501). The classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
PS23azz | AT2023dyp | 13:12:58.023 | +23:22:51.35 | 0.020 | II | +300d | (1)
ATLAS24api | AT2024uj | 11:07:49.060 | -20:01:34.25 | 0.013 | Ib-Ca-rich | +20d | (2)
PS24rv | AT2024ats | 12:56:54.996 | +27:44:12.83 | 0.03 | Ia-pec | +15d | (3)
Notes:
When the redshift is given to 2 decimal places, it is derived from the SN spectrum. Otherwise, the redshift is determined from the host galaxy.
(1) We measure a H-alpha FWHM of 4000 km/s.
(2) We find good matches to SN 2019ehk (Jacobson-Galan et al., 2020) at ~3 weeks post-maximum.
(3) We find good matches to SN 2002es (Ganeshalingam et al., 2012)and iPTF2014atg (Cao et al., 2015) at ~2 weeks post-maximum.
