About article:
CCD photometric observations of the dwarf nova V1006 Cyg were
carried out in 2015 -- 2017 with 11 telescopes located at 7 observatories.
They covered the 2015 superoutburst with rebrightening, five normal
outbursts of ∼4-day duration and one wide outburst that lasted
at least seven days. The interval between normal outbursts was 16 and 22
days, and between superoutbursts is expected to be longer than 124 days.
The positive superhumps with the mean period of 0d.10544(10) and
0d.10406(17) were detected during the 2015 superoutburst and
during the short-term quiescence between rebrightening and the start of the
first normal outburst, respectively. During a wide 2017 outburst the
orbital period 0d.09832(15) was found. The amplitude of this
signal was ∼2.5 times larger at the outburst decline than at its
end. During the quiescence stage between the first and the second normal
outbursts in 2015 we possibly detected the negative superhumps with the
period of 0d.09714(7). In all other cases of quiescence we
found only the quasi-periodic brightness variations on a time scale of
20--30 minutes with a different degree of coherence and a variable amplitude
reaching 0.5 mag in extremal cases.
