We present the results of our intensive photometric (BVR_CI_C passbands) and spectroscopic monitoring (high and low resolution) throughout the 2006 outburst of the symbiotic star and recurrent nova RS Oph. Photometrically as well as spectroscopically the 2006 event closely followed the pattern already traced by the previous outbursts that occurred in 1898, 1933, 1958, 1967 and 1985. The decline time scales in the B band were t₂ = 6.2 and t₃ = 17.1 d. Coronal emission lines reached maximum intensity around day ∼70. A fast drop in brightness set in at day ∼80 and brought the nova below quiescence mean level by day ∼90, where it is still now, varying widely both in brightness and color.
