[vsnet-rcb 816] Re: V854 Cen Another Apparent Decline Onset

[Peter F Williams]

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).

Recent visual observations:

    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.
