Photoelectric Observations of Southern Cepheids in 2001
A total of 2097 photometric observations in the BVIc systemare presented for 117 Cepheids located in the southern hemisphere. Themain purpose of the photometry is to provide new epochs of maximumbrightness for studying Cepheid period changes, as well as to establishcurrent light elements for the Cepheids.

New aperture photometry for 217 galaxies in the Virgo and Fornax clusters.
We present photo electric multi-aperture photometry in UBVRI of 171 and46 galaxies in the Virgo and Fornax clusters, respectively. Many of thegalaxies have not been observed in at least one of these passbandsbefore. We discuss the reduction and transformation into the Cousinsphotometric system as well as the extinction coefficients obtainedbetween 1990 and 1993.

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.

Secondary standards for the Stromgren UVBY system
Observations of 158 E region stars have been made in the Stromgrensystem, using the 46-cm reflector at Cape Town. They are mostly brighterthan eighth magnitude and are intended for use as secondary standardsfor the four-color system. The E region relative zero points are definedwith a precision of + or - 0.001 mag, and the internal standard errorsof the colors life between + or - 0.001 and + or - 0.002 mag.

The color-absolute magnitude relation for E and S0 galaxies. II - New colors, magnitudes, and types for 405 galaxies
Colors and magnitudes measured in the ubVr photometric system arepresented along with galaxy types and radial velocities for 405 E, S0,SB0, and Sa field galaxies. The color-aperture effect for E and S0galaxies is investigated together with the K-reddening due to redshiftand the aperture correction to V magnitudes. An average standardcorrected color reduced to an aperture ratio of 0.5 and a standard Vmagnitude corrected to an aperture ratio of 2.5 are given for eachgalaxy; the Galactic reddening as a function of latitude is derived fromthe corrected color data. The color-absolute magnitude (C-M) relationpreviously established for the Virgo cluster and nine other nearbygroups and clusters of galaxies is shown to apply equally to the presentsample of E and S0 field galaxies. It is concluded that whatever itscause, the C-M effect appears to be universal and may be useful for thedetermination of relative distances to galaxies in clusters, groups, andthe general field.
