The Southern Vilnius Photometric System. III. Observations of E and F Harvard Standard Regions, 47 TUC and Some Metal-Deficient Stars
The results of photoelectric photometry in the Vilnius system of 101southern stars in the areas E1--E4, E8, E9 and F1 as well as of somemetal deficient stars are presented. Photometrically determined spectraltypes and luminosity classes of these stars are also given.

Secondary UVBY standards in the Harvard E-regions
Photoelectric uvby photometry for 201 stars which are already UBV (RI)cstandards is presented. The photoelectric data are closely tied to theCousins uvby standards and the stars should be suitable for use asfainter (7-11 mag) secondary standards.

HD 47147 - A small-amplitude extreme metal-poor RRab pulsating variable
The photometric variations and physical and kinematical properties of HD47147, a ninth magnitude metal-deficient star, are discussed. The longperiod (0.79732 days), the small amplitude (0.17 mag in the visualband), and the mean effective temperature of 6160 K of this RR Lyraepulsating variable can be understood by its location near the red edgeof the instability strip. The extreme Population II characteristics ofHD 47147 are confirmed by its kinematical properties. The temperatureand the relatively high luminosity derived are consistent with bothpossibilities that HD 47147 is a red horizontal branch star or that itis a suprahorizontal branch star actually evolving redward toward theasymptotic branch. Its low amplitude suggests the possibility that thered edge of the instability strip corresponds to a smooth transitionfrom variable to non-variable stars.

UBV photometry of E region standard stars of intermediate brightness
Photometry data are given for 335 stars in the nine E regions.Observations were made using a photometer and filters on the 47 cmreflector at Cape Town. The stellar dispersions are summarized. Data arepresented in tabular form.
