We used the Expanded Very Large Array (EVLA) to observe the field of PTF10vgv (ATEL#2914) under our NRAO Target Of Opportunity program "Exploring Transients in the Local Universe". The EVLA observations were made on October 7.16 UT. We observed the source along with the necessary calibrators, simultaneously at frequencies of 4495 MHz and 7915 MHz for a total of 30 minutes. We detect no radio emission from the position of PTF10vgv to a 3-sigma limit of 120 uJy (4495 MHz) and 102 uJy (7915 MHz). At a redshift of z=0.015, we estimate the peak 5 GHz spectral luminosity of PTF 10vgv to be smaller than 6e26 erg/s/Hz. This limit is about 100-times below the luminous SNe 1998bw (Kulkarni et al. 1998) on a similar timescale. We note that the broad-line Ibc 2002ap (d=7.3 Mpc), studied by Berger, Kulkarni & Chevalier (2002) , was 20 times fainter than this limit.
