		Lick Shane telescope

We report the following classifications of optical transients from spectroscopic
observations with the Kast spectrograph on the Shane telescope. The targets
were supplied by ATLAS, ZTF and the Young Supernova Experiment. All observations
were made on 2025 Aug 22 UT. Classifications were performed with SNID (Blondin
& Tonry, 2007, ApJ, 666, 1024) and visual matching.

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 Si II 6355 velocity of -11,300 km/s. 
(2) We measure a Si II 6355 velocity of -11,400 km/s. 
(3) The spectrum is consistent with SN 2002cx with a phase of -4.5 days.
The blue side of the spectrum is well matched to that of SN 2002cx, while
the red side appears to be more affected by host-galaxy contamination.

(4) The H-alpha line exhibits a narrow component with a FWHM velocity of
approximately 450 km/s and an intermediate-width (or broad) component with
a FWHM velocity of roughly 2,450 km/s.
