R. Russell, R. Rudy, and B. Kaneshiro, The Aerospace Corporation; M. Skinner and S. Gregory, Boeing LTS; and M. Sitko, University of Cincinnati, report observations of V1280 Sco (Nova Sco 2007; cf. IAUC 8845) using the "Broadband Array Spectrograph System" (BASS; range 3-13.5 microns) on the 3.6-m AEOS telescope at Haleakala on Apr. 6 UT, and the NASA Infrared Telescope Facility 3-m telescope (+ SpeX; range 2.3-5.5 microns) on Apr. 27. These spectra exhibit detections of the unidentified infrared bands near 3.3, 3.4, 8, and 11.4 microns via BASS, and near 3.3 and 3.4 microns via SpeX, along with Brackett-alpha. The wavelengths are shifted per the studies of Geballe (1997, ASP Conf. Ser. 122, 119). These features are superposed on a fairly flat continuum from about 3 to 5 microns. If a single temperature were associated with the underlying continuum, it would be on the order of 600-650 K. After the initial BASS detection and subsequent SpeX confirmation, SpeX data from Oct. 2008 were examined more closely, and suggestions of the 3.3- and 3.4-micron features were seen.
