We derived its long term $I$-band light curve from the photographic archives of the Asiago and Catania Observatories, covering the years from 1965 to 1984. CCD $R_C$ photometry in Summer 2009 was re-analyzed. Optical spectra were secured at Loiano Observatory in 2011 and 2012. J H K photometry, obtained from several experiments in different epochs was compared and the Spitzer images were re-analyzed.\n  V2282 Sgr was found to be irregular variable in all wavelengths.
