The Palomar Transient Factory (see ATel #1964) reports the discovery of 25 optical transients with the Palomar Observatory 1.2-m Oschin telescope (+CFH12K camera). Imaging data were obtained on several nights between Mar 17 and Mar 28 with a g-band filter. Transient candidates were identified after subtracting off reference templates constructed from imaging data obtained prior to Mar 12. Spectroscopic follow-up was carried out on Mar 27, 28, 29, 30, and 31 with the 9.2-m Hobby-Eberly Telescope (+LRS), the 5.1-m Palomar Hale (+DBSP) telescope, and the 10.0-m Keck-I (+LRIS) telescope. Below we list the locations of each transient, the UT date in which the transient was first found, and the g-band magnitude at discovery.
