B and V CCD photometry from 1984 through 1994 is presented for 50 RR Lyrae stars and two red variable stars in the globular cluster NGC 7006. New determinations of pulsation periods and period change rates are given and used to plot B light curves. T

28 Aquilae (HR 7331, V1208 Aql) was first announced as a δ Scuti type variable by Breger in 1969 with a period of about 0.15 day. It was clear that the light variability could not be adequately represented as a sinusoidal variation with just one fre

B and V CCD frames of the globular cluster NGC 7006 have been obtained to study the period change rates and determine photometric colours for the RR Lyr variables.

Period change rates are presented for 46 RR Lyrae stars in the globular cluster NGC 7006 based on previously published photometry of photographic plates taken in the 1930's and 1950's by Hubble and Sandage, and new photometry of 35 photographic plate

Visual magnitudes have been measured for 20 variables on 32 plates of M28. These have been combined with previously published as well as newly determined blue magnitudes in order to obtain colors for the variables. Blue and visual light curves are pr

Observations of the globular cluster M80 obtained between 1939 and 1987 are examined. The observations have resulted in the discovery of ten variable stars in or near the cluster. The colors and periods of these variable stars are discussed. For the

Magnitudes for the seven RR Lyr variables and one red variable in NGC 5897 have been derived from 213 B plates taken from 1939 through 1987 and from 38 V plates taken from 1956 through 1987. Blue light curves have been constructed for all the periodi
