Good morning,
The bright southern RCB star V854 Cen has shown a gradual fading over the past 2 weeks, suggesting the possible onset of a deep decline may have commenced. This star was at visual magnitude 8.0 last night (May 18), a half magnitude below its normal maximum brightness. Typically, if it fades to magnitude 8.5 it will continue onto a deep decline. Observations over the next few days will confirm if this does indeed occur. The previous deep decline commenced in July 2022. Recent visual observations of V854 Cen:
