It would appear that the decline is continuing.

I made it 8.3 tonight 01/08/2013.

Further to (vsnet-rcb 813) and (vsnet-rcb 810) below, V854 Cen has again
fallen to magnitude 8 in what may be another apparent decline onset.
Interestingly, this current fall to magnitude 8 is very close to the
generally accepted 43 day pulsation cycle for this star relative to the
earlier dip reported in (vsnet-rcb 810).

The RCB star V854 Cen may have commenced to decline as indicated by the
following visual observations:

 

CENV854    20130526.353    74    WPX

CENV854    20130603.423    74    WPX

CENV854    20130610.490    74    WPX

CENV854    20130613.427    76    WPX

CENV854    20130616.441    80    WPX

 

If this star continues to fade it will be 13 months since the previous deep
decline of 2012 May.
