Study of Neglected Variable Stars Classified as Type II Cepheids
Four variable stars classified as Type II Cepheids have been studiedpartly based on new photometry and the Hipparcos photometric data. Thecorrect period is derived for V341 Ara and NW Pav and it is pointed outthat RR Mic and V1711 Sgr do not belong to Type II Cepheids, insteadthey may be semi-regular variables. The cycle length of theirvariability is also determined.

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.
