We are monitoring the recent nova V1723 Aql (IAUC #9166, 9167) with the Expanded Very Large Array (EVLA) at ~5, 6.75, and 32 GHz. Our first observations took place on Sept 25, two weeks after the start of the outburst (which we take to be Sept 11, 2010); we measure a flux density of 0.4 +/- 0.1 mJy at 32 GHz and a non-detection at 6.75 GHz (rms ~ 11 microJy/beam). Our most recent measurements were on Oct 14/15 with measured flux densities of 3.0 +/- 0.6 mJy at 33 GHz and 0.6 +/- 0.1 mJy at 5.25 GHz. The nova is evolving rapidly, with the spectral index &alpha (S&nu &prop &nu&alpha) changing from 1.5 to 0.9 between Oct 6 and Oct 14/15.
