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