The 15-th mag magnitude in some catalogs refers to an incorrect quiescent identification by Khatisov, A. S. (1971) Byull. Abatsumani Astrofiz. Obs., 40, 13, which referred to a GSC 2.2 star at 06:25:19.69 +05:26:32.9 (J2000.0). The actual location of KT Mon is void of a quiescent counterpart down to mag 20. I have once attempted to make an Ic-band identification, but nothing was evidently identified. Abstract from Kato and Yamaoka (2002) A&A 396, 629 is attached below. The preprint can be accesible at the VSNET preprint archive: http://vsnet.kusastro.kyoto-u.ac.jp/pub/vsnet/preprints/KT_Mon/ Taichi Kato == KT Mon has been considered as a classical nova in 1942 based on its light curve and spectroscopy. However, we noticed a unusual feature for a nova soon after its maximum: the early presence of high excitation emission lines such as He II and N III. We propose previously overlooked interpretations that KT Mon can be either a WZ Sge-type dwarf nova and an X-ray transient, although the possibility of an unusual or a recurrent nova is not completely excluded. If KT Mon is a WZ Sge-type dwarf nova, the system is expected to have a brown dwarf secondary. If KT Mon is an X-ray transient, the system is a good candidate for the nearest black-hole binary. Within our knowledge, the observed features seem to more strongly support the latter possibility. In all possibilities, we can expect a recurrent outburst in meaningfully near future.
