We obtained optical spectra (4000-10000 A) of PSN J09430082+3146486 and PS1-14xx using the SED-Machine mounted on the Palomar 1.5-m Telescope. We report the following classifications using superfit (Howell et al. 2005, ApJ 634, 1190):

 
Name                  |     RA      |     Dec     | Spec. Date | Type | Redshift | Notes 
PSN J09430082+3146486 | 09:43:00.82 | +31:46:48.6 |   May 4.3  |  IIb |  0.022   |   1 
PS1-14xx              | 17:44:12.25 | +50:33:04.6 |   May 4.5  |  Ia  |  0.018   |   2 

1) The best matches are to SN 1997dd and SN 1993J. We tentatively identify He I 6678 and 7065 lines, which suggest a phase 2-3 weeks after explosion. The redshift is from the host galaxy (via. NED).

2) The phase is likely around 2 weeks after maximum light. The redshift is from the host galaxy (via. NED).

The SED-Machine is currently being commissioned. The results reported here should therefore be taken as preliminary.
