We report the following classifications from spectroscopic observations with the LRIS spectrograph on the Keck I telescope, made on 2022 Sep 22 UT. The targets were supplied by Pan-STARRS and the Young Supernova Experiment (YSE) and ZTF. The classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).

PS22iwi | AT2022uwr | 01:08:10.73 | -14:45:41.14 | | | | (2)
Notes:
(1) We measure an H alpha velocity of -7,000 km/s
(2) We detected a blue continuum with an emission line at 4200 A, observed wavelength.
