Infrared photometry inJ. H, K, L, M bands carried out in different years from 1983 to 1986, andU, B, V, R, I quasi-simultaneous to 1984 are presented. Although the amplitude of the minima decrease as the wavelength increase, the infrared light curves show a similar behaviour to that observed in visible. Since no variations in the average magnitudes are notted from 1983 to 1986, we could assumed that the activity of II Peg is not increasing. Also from the light curves a concentration process of the spots seems to have taken place from 1984 to 1986. In the analysis of the infrared colours an excess attributable to circumstellar dust emission is found.
