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.

Photometric reductions and the lightcurve of (51) NEMAUSA
The light curve of the minor planet (51) Nemausa is derived on the basisof 1779 photoelectric (B and V) observations and a photometric reductionusing a rigorous least squares method. Separate light curves are givenfor the B and V observations, respectively. An absolute B-V magnitudefor (51) Nemusa of 0.787 + or - 0.004 mag was estimated. A detaileddescription of the least squares method is presented.

UBV photometry of short period cepheids
613 UBV observations of 15 pulsating variables collected on the 1 mreflector at ESO, La Silla, Chile are reported. The variables observedhave periods between one and three days.

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.
