Abstract:
Photoelectric UBV photometry is presented for over 400 HD stars which
lie within about a degree of selected cataclysmic variables. The data
will be combined with polarimetry to determine the distances of the
CVs.

Note (1): HD 89945 : Variable. Observed range in V∼0.28mag; 5 observations.
HD 112343 : Identification uncertain. The fainter star (V=10.166) is
presumably the correct star (HD type G5) and the
brighter star is probably CD -29 10021.
HD 116997 : Possibly variable. Observed range in (U-B)∼0.1mag;
2 observations.
HD 118257 : Possibly variable. Observed range in V∼0.05mag;
2 observations.
HD 154001 : Possibly variable. Single observation in 1991 different by
0.1mag from mean of 4 observations in 1992.
HD 154882 : Pobably variable. Observed range in V∼0.1mag;
4 observations.
HD 154936 : Pobably variable. Observed range in V∼0.09mag;
6 observations.
HD 165761 : Variable. Observed range in V∼0.18mag; 4 observations.
HD 174107 : = V603Aql ! Two observations with mean V=11.44 are clearly
of the CV itself. The two observations at V=9.95 are
presumably of the wrong object although there is no star
of such brightness within several arc minutes of
V603 Aql (Duerbeck, 1987SSRv...45....1D 1987SSRv...45....1D, p. 163)
HD 186669 : Probably variable. Observed range in V∼0.09mag;
2 observations. Listed as V3960 Sgr in the General
Catalogue of Variable Stars (Kholopov et al., 1990,
Cat. II/139) Type LB (M5/7)
HD 197010 : Variable. Observed range in V∼0.13mag; 7 observations.
HD 197042 : Variable. Observed range in V∼0.13mag; 7 observations.
HD 216482 : Close pair. The brighter star is presumably HD 216482
(=BD -3 5524) and the fainter star is then BD -3 5525.
