We triggered our NRAO Target Of Opportunity program "Exploring Transients in the Local Universe" and used the Expanded Very Large Array (EVLA) to observe PTF10abyy (ATEL#3091), a young Type II supernova discovered by the Palomar Transient Factory. The EVLA observations were made on 2010 December 10.28 UT. We detect no radio emission at a center frequency of 8.46 GHz down to a 3-sigma limit of 81 uJy.

Under our ongoing PTF/Swift program, we began observations of PTF10abyy on December 10.41 UT. We measure the following Swift/UVOT (Vega) magnitudes for the transient: U=16.0, UVW1=15.5, UVM2=15.3, UVW2=15.3. Further monitoring is ongoing.

We thank the EVLA team and the Swift team for promptly undertaking these target of opportunity observations.
