Outburst Behaviour of the Dwarf Nova CG Draconis

Abstract: During the British Astronomical Association (BAA) 2022 campaign, 27436 photometric observations of the dwarf nova (DN) CG Draconis were made, with 106 eclipses recorded. This work summarizes the new data available and provides updated ephemeris and commentary on the observed eclipse profiles. The orbital period found is = 4 h 31 m 38 s ± 1 s . Two types of quasi-periodic outbursts are identified: normal outbursts, of Δ ≈ 1.25 mag amplitude, and bright, of Δ ≈ 1.5 mag. The pattern resembles superoutbursts of SU… Show more
