Hi Andrew,

Great to see someone keeping a regular watch on these southern RCB stars!

CC to the vsnet-rcb and vsnet-alert groups for info, but I cannot remember if they accept the light curve attachments J

Tks and regards

Hi All

The little observed RCB star, V653 Sco, is undergoing a decline as can be seen from the attached light curve.

Years ago, professional astronomers used to be very interested in RCB fades.  That doesn't seem to be the case anymore at least that I'm aware of.

Regards

Andrew
