The Type Ia supernova science working group of the Palomar Transient Factory (ATEL#1964) reports the discovery of three nearby supernova. Confirmation spectra were taken on the Keck I 10-m telescope (+LRIS) on May 15 UT of PTF10hdv and on the Double Beam Spectrograph at the Palomar Hale telescope on May 21 UT by I. Arcavi, S. Ben-Ami, A. Sternberg, A. Gal-Yam and D. Xu (Weizmann Institute of Science). A spectrum of PTF10icb was taken by D.A. Howell on Gemini North on June 2 UT. Classification of the spectra were carried out using Superfit (Howell et al. 2005). As all three were quite young, STIS/UV spectroscopic observations on the Hubble Space Telescope were triggered by the ToO program "Verifying the Utility of Type Ia Supernovae as Cosmological Probes: Evolution and Dispersion in the Ultraviolet Spectra " (PI: R. Ellis). We strongly encourage additional follow-up of these sources at all wavelengths.
