G'day all,

This would be a good one for my observing list.  Is there a comparison
star sequence available?

Another bright and neglected RV Tau-type is RU Cen.  The GCVS lists a
range of 8.7-10.7P, and a period of 64.7 days was determined in 1935(!)
My notes suggest a visual range of 8.2-10.3, but I don't have enough
observations to derive a good period.  Is anyone else watching this star
who can supply me some data?

Interestingly, one more "neglected" (by VSS RASNZ standards) RV Tau-type
is R Sct.  Too far north for us... <g>



cheers,
