Dear colleagues,
An analysis of the 1432-0033 = Vir4 CCD data sets of CBA Belgium and CBA Pakuranga, securely has revealed the existence of eclipses in this newly detected [see VSNET-ALERT 5037] UGSU type dwarf nova. Data were obtained on June 26/27 (CBA Belgium), June 28/29 (CBA Belgium), June 29 (CBA Pakuranga) and June 30, 2000 (CBA Pakuranga).
Eclipse profiles have an average depth of 0.9 mag and a duration of approx. 15 min (visual inspection of light curve!). The orbital period of 1432-0033, derived from eclipse timings spread over the period mentioned above, is 0.0726 d. More precise values will be communicated after a detailed analysis of all available data has been carried out.
Best regards,
Tonny Vanmunster (CBA Belgium)
Fred Velthuis & Jennie McCormick (CBA Pakuranga)
