Rapid Variations in V2275 Cyg (Nova Cyg 2001 #2)
  We present time-resolved CCD photometry of V2275 Cyg 790 days after the nova outburst. The data show a 20% peak-to-peak oscillation with a period of 24 minutes. The period appears stable over the two nights of observation, but QPO can not be ruled out.
