On the Photometric Variability of Red Clump Giants
Hipparcos photometry of the 308 red clump giants identified by Paczynskiet al. (1999) is investigated. These stars are found to be quite stableduring the three years of observation, but questions remain about longerterm stability.

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.
