We observed the 2015 July-August long outburst of V1006 Cyg and established this object to be an SU UMa-type dwarf nova in period gap. Our observations have confirmed that is second showing three types outbursts (normal, normal superoutbursts) after TU Men. succeeded recording growing stage superhumps (stage A superhumps) obtained a mass ratio 0.26-0.33, which close stability limit tidal instability. This identification demonstrated indeed slowly grow systems near limit, idea first...
We present a result of the multi-longitude campaign on photometric investigation SU UMa-type dwarf nova in period gap, V1006 Cyg 2023.It displayed long-lasted standstill (a feature Z Cam-type stars) terminated by long outburst IW And stars).The did not have superhumps SS Cyg-type but showed orbital 0.09837(22) d periodicity instead.Color-color diagrams indicate that layers disk different temperatures contribute to total radiation system.In particular, large contribution from innermost hot is...
We report on follow-up studies of transient events and objects, which have been conducted in recent years using ground-based optical observations.BVRI photometry has performed with small medium-sized telescopes located Europe North America.The purpose these studies, are mainly focused objects unknown nature, is to reveal features 206 V. Godunova et al.their variability that critical for classifying the transients understanding their evolution.We present here some results obtained from...
CCD photometric observations of the dwarf nova V1006 Cyg were carried out in 2015-2017 with 11 telescopes located at 7 observatories. They covered 2015 superoutburst rebrightening, five normal outbursts ~4-day duration and one wide outburst that lasted least seven days. The interval between was 16 22 days, superoutbursts is expected to be longer than 124 positive superhumps mean period 0^d.10544(10) 0^d.10406(17) detected during short-term quiescence rebrightening start first outburst,...
