According to Semkov et al. (ATEL #4180) V2492 Cyg started rebrightening:
"The photometric observations obtained with the 2-m telescope of the National Astronomical Observatory Rozhen (Bulgaria) on the night of June 14/15, 2012 gives the following magnitudes: I=15.92, R=17.61, V~20.0
(...) This repeated outbursts within two years indicate a similarity with the photometric variability of another eruptive PMS object V1647 Ori."
