Subjects: Infra-Red, Nova We report RIJHKLM photometry of Nova Del 2013 taken on August 28.13 UT using an As:Si bolometer mounted on the 0.76-m infrared telescope of the University of Minnesota's O'Brien Observatory (Marine on St. Croix, Minnesota, USA). Vega (alpha Lyrae) was used as the standard star. On this date we find: R = 5.6 +/- 0.1, I = 5.2 +/- 0.1, J = 4.5 +/- 0.1, H = 4.7 +/- 0.1, K = 4.7 +/- 0.1, L = 3.3 +/- 0.2, M = +1.8 +/- 0.3. The deviations from an optically thin free-free slope are consistent with reports that strong near-IR hydrogen emission lines are present in the spectrum ( see ATELs 5336 and 5337). Our observations were made possible by a generous gift from Edward Glickman and technical support by A. Knutson and J. Marchetti.
