We report the discovery and spectroscopic classification of three new supernovae from PTF (ATel #1964; http://www.astro.caltech.edu/ptf). The supernovae were discovered by Oarical, an autonomous software framework of the PTF collaboration, based on observations made with the Palomar 48-inch Oschin Schmidt telescope. Spectroscopy was undertaken with the Double-Beam Spectrograph (DBSP; Oke & Gunn 1982, PASP, 94, 586) on the Palomar 5-m Hale telescope on December 13 UT. The superfit (Howell et al. 2005, ApJ 634, 1190) program was used to determine the classifications.

Details of the discoveries are as follows: <table border="1"> <tr> <th>Name</th> <th>RA</th> <th>Dec</th> <th>Disc Date (UT)</th> <th>Disc Mag (r)</th> <th>Type</th> <th>z</th> </tr> <tr> <td>PTF10aauo</td> <td>09:59:54.26</td> <td>+68:06:02.5</td> <td>Nov 7</td> <td>19.0</td> <td>SN II</td> <td>0.035</td> </tr> <tr> <td>PTF10aauu</td> <td>09:29:56.74</td> <td>+35:21:52.6</td> <td>Nov 13</td> <td>18.8</td> <td>SN II</td> <td>0.044</td> </tr> <tr> <td>PTF10acbu*</td> <td>14:00:46.92</td> <td>+59:20:16.5</td> <td>Nov 15</td> <td>18.1</td> <td>SN Ic</td> <td>0.009877</td> </tr> </table> * Originally announced by Guoyou Sun and Xing Gao (CBET 2486) with a discovery date of Oct 03.605 UT (see also CBET 2600).
