Pre-outburst detections of Nova Delphini 2013 from iPTF
Abstract
We report pre-outburst detections of Nova Delphini 2013 (CBET #3628) from the intermediate Palomar Transient Factory (iPTF; ATel#4807). We are undertaking a Halpha narrow band survey during bright time at the Palomar 48inch telescope. Two narrow band (about 7nm) filters are used in the survey, with central wavelengths of 656nm and 663nm, respectively. Each exposure is 60s, and the limiting magnitude is about 18 (AB).
