We report Visual and Near-IR photometry of Nova Del 2013 taken at the University of Minnesota's O'Brien Observatory (Marine-on-St-Croix, Minnesota, USA).
VRIJHKLM photometry were obtained on two successive nights using an AsSi bolometer. Vega (alpha Lyrae) was used as the standard star. Our photometry show:
August 16.2 UT: V = 4.8 +/- 0.1, R = 5.4 +/- 0.1, I = 5.2 +/- 0.1, J = 4.4 +/- 0.1, H = 4.3 +/- 0.1, K = 4.3 +/- 0.1, L = 4.5 +/- 0.2.
August 17.15 UT: V = 4.2 +/- 0.1, R = 4.7 +/- 0.1, I = 4.5 +/- 0.1, J = 4.3 +/- 0.1, H = 3.9 +/- 0.1, K = 3.9 +/- 0.1, L = 3.9 +/- 0.15, M = 3.5 +/- 0.2. On this date the nova clearly seems to be in a free-free emission phase,
becoming optically thick at ~ 2 microns.
These observations were made possible by a generous gift from Edward Glickman and technical support by A. Knutson and J. Marchetti.
