Abstract
We present near-infrared photometry of two objects that have been clas sified as classical novae: CK Vulpeculae and V605 Aquilae. We were sur prised to find that CK Vul was a moderately bright near-infrared sourc e (m(K)=14.13). Infrared images conclusively show that the near-infrar ed source is positionally coincident with the optical candidate for CK Vul. We are able to model the near-infrared + IRAS spectral energy di stributions of both objects with a two-component model composed of a h eavily extinguished central source, and a cooler blackbody source cons istent with a cool dust shell. The combination of the model results an d the outburst parameters suggest that these two objects might be of a similar nature. If we are to make this association, however, the cent ral source luminosity of CK Vul object must have declined dramatically since the eruption in 1670. Because of its brightness, near-infrared spectroscopy of the CK Vul counterpart should be easily achievable wit h current instrumentation. Such observations are needed to determine t he true nature of this source.
