Nova Delphini 2013于2013年8月14日被发现，并最终成为一个肉眼可见的物体。我们试图研究该天体在爆发前的行为，并将其与其他新星爆发前的光度特征进行比较。我们搜索了Pan-STARRS 1卫星，以确定Nova Del 2013爆发前的测光，并确定了爆发前1.2年的24次观测。海豚座新星的祖先显示出十分之几等的变化，但与档案板测光相比并没有显着变亮。我们还发现，在Pan-STARRS 1观测对之间的大约半小时时间尺度上，该对象没有显着变化。
Nova Delphini 2013 was identified on the 14th of August 2013 and eventually rose to be a naked eye object. We sought to study the behaviour of the object in the run-up to outburst and to compare it to the pre-outburst photometric characteristics of other novae. We searched the Pan-STARRS 1 datastore to identify pre-outburst photometry of Nova Del 2013 and identified twenty-four observations in the 1.2 years before outburst. The progenitor of Nova Delphini showed variability of a few tenths of a magnitude but did not brighten significantly in comparison with archival plate photometry. We also found that the object did not vary significantly on the approximately half hour timescale between pairs of Pan-STARRS 1 observations.
