NN Cam is in outburst on three unfiltered 120-sec images taken last
night from Ka-Dar observatory's TAU station (40-cm Djigit telescope,
remotely by Vladimir Gerke). Using R=12.3 comparison star from the
finder chart at http://hea.iki.rssi.ru/~denis/NSV1485-comps.gif I have
measured the magnitude of the variable to be 12.42! It is the
brightest outburst of this star I have ever seen, beyond the reported
range 12.6-17.8.

Recent observations of NN Cam from Caucasus:
