UBV photometry of stars whose positions are accurately known.
Photometric indices V, B-V, and U-B were measured for about 560 stars ofthe AGK3R and NPZT catalogs between BD declinations 11 deg and 23 deg,using the 40-cm Cassegrain telescope of the Kvistaberg Observatory fromApril 1986 to May 1987. The observation procedure and the reductiontechnique were the same as in the earlier papers of this series by Oja(1984, 1985, 1986, and 1987). The mean errors were calculated from theinternal consistency of the data. The accuracy was found to be the sameas for the earlier parts of the survey.
| Photoelectric observations of lunar occultations
Photoelectric observations of 13 lunar occultation disappearances duringa March 1979 Hyades passage are reported. Three double stars (SAO 93925= Fin 342 = 70 Tau, SAO 93961 = ADS 3248, and SAO 95419 = Kui 24) andone possible double (SAO 93950 = 75 Tau) were detected. A briefdescription is given of the Purdue University pulse-counting photometeras modified for occultation observations.
