Hi Marcos, V854 Cen is perhaps the most active of the RCB stars and would seem ready for a deep decline, if not overdue. I have noticed its SR variations having a marginally greater amplitude during June and July and that has in previous cases led to a decline onset. My most recent observation was on Thursday, July 28.432UT at magnitude 7.5. That is marginally fainter than usual and with your most recent magnitude of 7.9, it may well indicate the onset of a decline. It will sometimes stall near magnitude 8 and return to maximum but if it goes below magnitude 8.5 then a deep decline is most likely underway. Hopefully the twilight clouds will clear tonight!

Dear VSS friends, last night i observed the RCB star V0854 Cen fainter than the comparison star of mag 7.5. I have observed it here again now and estimated the magnitude of 7.9, we have some cirrus here at the moment, so the star could be a little bit brighter (7.8 or 7.7). But it is still fainter than 7.5 and brighter than 8.2. I'm warning you because this could be the beginning of a fading of the star. -- You received this message because you are subscribed to the Google Groups "Variable Stars South" group.

[vsnet-rcb 865] V0854 CEN FADING
by Cledison Marcos da Silva 31 Jul '22

31 Jul '22

Hello friends from VSNET.I've been following V0854 Centauri since the beginning of the year, more frequently since April. On the night of 07/28 I noticed that it was dimmer than the 7.5 magnitude comparison star. As the days passed it continued to decline. Being today close to magnitude 8.5, approximately 2.5 times dimmer than the day I noticed the drop. After my warning, other observers confirmed the fall, Antonio Padilla Filho, Moisés Montero Reyes Ortíz, Eurimar Araujo, Paulo Reis Fernandes, Daniel Jose Mendicini and Peter F Williams. There is a small possibility that the star will regain its brightness and go back to "max", but what we are seeing appears to be a deep minimum of it. The last one was in 2020 (left corner of the light curve), it was not a deep minimum, as it can get close to magnitude 15.

Hi Marcos and All, As noted below, the RCB star V854 Cen may have commenced to decline (10x50mm binoculars): CENV854 20220717.386 74 WPX CENV854 20220724.420 73 WPX CENV854 20220727.410 74 WPX CENV854 20220728.432 75 WPX CENV854 20220730.368 81 WPX Also, the RCB star S Aps is also fainter than usual tonight and may have commenced to decline (20x80mm binoculars): APSS 20220717.418 95 WPX APSS 20220724.465 97 WPX APSS 20220727.454 97 WPX APSS 20220728.403 96 WPX APSS 20220730.429 100 WPX Further observations will confirm if either or both of these stars continue into a deep decline. Tks and regards Peter Williams Heathcote NSW From: 'Peter Williams' via Variable Stars South [mailto:VariableStarsSouth@googlegroups.com] Sent: Saturday, 30 July 2022 5:37 PM To: VariableStarsSouth(a)googlegroups.com Subject: RE: [VSS] V0854 CEN fading? Hi Marcos, V854 Cen is perhaps the most active of the RCB stars and would seem ready for a deep decline, if not overdue. I have noticed its SR variations having a marginally greater amplitude during June and July and that has in previous cases led to a decline onset. My most recent observation was on Thursday, July 28.432UT at magnitude 7.5. That is marginally fainter than usual and with your most recent magnitude of 7.9, it may well indicate the onset of a decline. It will sometimes stall near magnitude 8 and return to maximum but if it goes below magnitude 8.5 then a deep decline is most likely underway. Hopefully the twilight clouds will clear tonight! Tks and regards Peter Williams From: variablestarssouth(a)googlegroups.com <mailto:variablestarssouth@googlegroups.com> [mailto:variablestarssouth@googlegroups.com] On Behalf Of Marcos Silva Sent: Saturday, 30 July 2022 8:03 AM To: Variable Stars South <VariableStarsSouth(a)googlegroups.com <mailto:VariableStarsSouth@googlegroups.com> > Subject: [VSS] V0854 CEN fading? Dear VSS friends, last night i observed the RCB star V0854 Cen fainter than the comparison star of mag 7.5. I have observed it here again now and estimated the magnitude of 7.9, we have some cirrus here at the moment, so the star could be a little bit brighter (7.8 or 7.7). But it is still fainter than 7.5 and brighter than 8.2. I'm warning you because this could be the beginning of a fading of the star. -- You received this message because you are subscribed to the Google Groups "Variable Stars South" group.
