We report VLA and CARMA observations of Nova Del 2013 (CBET #3628) from 2013 August 16. These observations span 4.6--96 GHz and yield non-detections:

UT Time FreqFlux Density
(GHz)(mJy)
Aug 16.15   4.6 -0.001 +/- 0.010  
Aug 16.15 7.4 -0.004 +/- 0.007
Aug 16.19 28.20.016 +/- 0.028
Aug 16.19 36.50.030 +/- 0.028
Aug 16.34 95.70.53 +/- 0.22

Assuming that the nova ejection took place on 2013 Aug 14.0 at 2300 km/s (ATel #5282), and the ejecta have a temperature of 10^4 K, the 3 sigma upper limit at 95.7 GHz yields a lower limit on the distance, > 2 kpc (consistent with optical distance estimates; ATel #5297).

We plan to follow the radio/millimeter evolution of this nova with additional multi-frequency observations.
