Photometry of Nova V 1493 Aql
We report on photometric observations of V 1493 Aql during the earlydecline and highlight some uncommon aspects of the light curve. V 1493Aql was hotter at maximum light than in the following phases, and wascharacterized by the presence of a long lasting secondary maximum, that,unlike in other novae, was quite red in color. The mean of threedistance estimates yields d ~ 18.8+/- 3.6 Kpc. Such a large distancewould place V 1493 Aql at the extreme outskirts of our Galaxy or even inan external Local Group galaxy. Based on data collected at theOsservatorio Astrofisico di Catania, stazione M. G. Fracastoro, Serra laNave (Etna), Italia
