Doug Welch mentioned in the AAVSO Legacy Stars LPVS topic that, "there are also newly discovered and confirmed R CrB stars that need to have sequences defined and monitoring started!"
I think this is a good idea, but quite offtopic on the Legacy LPVs topic, so it's time to start a new topic for RCB variables.
After some discussion with Doug I made sequence for two new RCB stars:
ASAS J190640-1623.9: listed as ASAS-RCB-8 in Clayton's paper. This is a 10.89V star in maximum, and a 1.38 magnitude fading was observed by ASAS-3 around 2001-2002. T Sgr and R Sgr lie not far from this star, so LPV fans can easily include this star into their programme.
NSV 8353: This star can be found in Ophiuchus, at -21 degress, so especially southern observers can monitor NSV 8353. According to VSX the amplitude of this RCB variable is: 12.6 - <14.1V. The light curve of ASAS-3 show some fadings down to 14.1V.
