Recent high-energy observations (ATEL#1426) report the onset of a new X-ray outburst of the binary X-ray pulsar 4U 0115+63. Our optical and NIR monitoring results show remarkable similarity of its current behavior to that observed during previous major outburst of 2004 September (see Reig, Larionov, Negueruela et al., 2007, A&A, 462, 1081), in the sense that the X-ray outburst occurs when optical level is close to its maximum (currently R~13.6), following several months of enhanced activity.
