This observational material was taken at the Observatories of the Astronomical Institute of the Slovak Academy of Sciences at the Stara Lesna (SL) and Skalnate Pleso (SP), as well as at the Astronomical Station of the National Observatory of Athens at Kryonerion (KR). The observations were carried out in 25 runs (24 nights) during the period from December 4th 1996 to November 25th 1998 in 112 hours of pure observational time. At the observatories SL and SP identical Cassegrain telescopes with a diameter of 60 cm were used. The observations of KR were performed by the same type of telescope with diameter of the primary mirror 120 cm. An one-channel photoelectric photometer with digital converter was used, as well as standard UBV Johnson's filters. All observational data, collected in table 4 are in the form of phase and magnitude for U, B and V colours. For determination of the phase, a newly derived ephemeris was used (this paper): MinI = HJD 2451143.27313 + 0.93125953 x E2001A&A...373..950Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/373/950CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/373/950https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/373/950http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/373/950https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/373/950https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/373/950http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/373/950GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/373/950/table4Photoelectric UBV magnitudes of KW PerrecnoRecord number assigned by the VizieR team.
