[vsnet-alert 19941] Re: [VSS] Another Possible Fading of V854 Cen

[Peter Williams]

Hi Andrew and All

 

Further to the below emails, after showing a slight fading during May and remaining near magnitude 8 during much of June, the RCB star V854 Cen is clearly fainter tonight and may have commenced to decline, as per the below visual observations.  As V854 Cen generally fades very quickly, further observations over the next few days should confirm if this the onset of a deep decline.

Hi Andrew and All,

 

Yes, I too have noticed V854 Cen being a little fainter than usual in recent days.  If it falls below magnitude 8.5 then it may well continue into a deep decline.

 

Let’s hope the weather cooperates over the next week or so.

 

Tks and regards

Hi All

 

The active RCB star, V854 Cen, maybe in the initial stages of another fade based on my recent observations:

 

June 10.558 UT  7.6

June 14.568 UT  7.9

June 15.585 UT  8.1

 

This may only be a small dip, but I'd encourage everyone to follow this star.  If it's a more significant fade then these tend to be very rapid events.

 

Regards
