Further to S. Shurpakov et al. (ATel #4805) we report the spectroscopic classification
of the transient MASTER OT J133253.32+355733.3. A spectrum obtained at the 4.2m William
Herschel Telescope (+ISIS) (range 350-950nm) on 2013 Feb. 13.26 UT and fitted using SNID
(Blondin and Tonry 2007, Ap.J. 666, 1024) shows reasonable matches to Type-Ia supernovae
between -5 days and peak magnitude at z=0.06. Given the redshift the host galaxy is faint
at M_g ~ -14.6.
We also report the spectroscopic classification of PSN J13275489+3022294
which was discovered at an unfiltered magnitude of ~19.2 on 2013 Jan. 24.90 UT in
the Tsinghua University-NAOC Transient Survey (TNTS) (http://www.cbat.eps.harvard.edu/unconf/followups/J13275489+3022294.html). A spectrum obtained from the WHT+ISIS (range 330-975 nm) on 2013 Feb. 10.13 UT and fitted using SNID best matches several normal Type-IIP supernovae 2-4 weeks after explosion.
