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 Freq Flux Density (GHz) (mJy) Aug 16.15 4.6 -0.001 +/- 0.010 Aug 16.15 7.4 -0.004 +/- 0.007 Aug 16.19 28.2 0.016 +/- 0.028 Aug 16.19 36.5 0.030 +/- 0.028 Aug 16.34 95.7 0.53 +/- 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.
