Abstract: Young double star V1318 Cyg has very unusual photometric and spectral behavior. We analyze its historical lightcurve and show, that the southern component V1318 Cyg S after being rather bright (13–14 magnitude in V) in 70ies started to lower brightness and in the 1990 became practically invisible in optics and very faint in IR. After its reappearance in the second half of 90ies the star very slowly raised its brightness. In 2016 we found that V1318 Cyg S again brightened up to 7 magnitudes in visible light. We present the new photometric data and discuss its spectrum. V1318 Cyg S can be an extreme case of EXors or even belong to some intermediate class between EXors and FUors.
