Photometries of B, V, Rc, Ic, y, J, and Ks bands and low dispersion opticalspectroscopic observations of Nova V1280 Sco, started soon after the outburst,are reported. We show that V1280 Sco is an Fe II nova and it is going throughthe historically slowest spectroscopic evolution. The rapid decline observed inthe early phase was caused by formation of a dust shell. We estimate theabundances of CNO using the absorption lines on a spectrum at pre-maximum, andfind over-abundances by [C/Fe] ~ 1.4, [N/Fe] > 2.0 and [O/Fe] ~ 1.1.
