R. W. Russell, E. A. Laag, and R. J. Rudy, Aerospace Corporation; and M. A. Skinner and S. A. Gregory, Boeing Corporation, report 3- to 14-micron spectroscopy of V496 Scuti (cf. IAUC 9093) and V5584 Sgr (cf. IAUC 9089) on Feb. 10 using the Aerospace Corporation's Broadband Array Spectrograph System on the 3.6-m AEOS telescope. Both novae have formed dust since previous observations in December. Thermal emission from this dust dominates the infrared continuum in both objects. The dust temperatures are 1200 ± 100 K for V496 Sct and 880 ± 50 K for V5584 Sgr. There is no evidence for carbon-monoxide emission in V496 Sct, and it is likely that the period of CO emission reported previously for this object (IAUC 9099, CBET 2069) has ended.
