WW Cet : faint standstill

 A Z Cam-type dwarf nova WW Cet has been in standstill
since 2012 Sept. As reported in vsnet-alert 13638, this
object was oscillationg in 2011, getting fainter gradually.
This object seems to continue oscillating in 2012, and
seems to have reached the minimum on 2012 Sept. After that,
this object appears to start standstill.
 As interesting respects, this standstill may not occur
after an outburst, but after reaching the minimum. This is
unusual for Z Cam type dwarf novae. And the standstill
magnitude is fainter than 2011 case by 1 mag.
