The 2011 February superoutburst of the dwarf nova SDSS J112003.40+663632.4
Jeremy Shears, Steve Brady, Tom Krajci +4
We report unfiltered photometry of SDSS J112003.40+663632.4 during the 2011 February outburst which revealed the presence of superhumps with peak-to-peak amplitude of up to 0.22 ma…
The orbital and superhump periods of the SU UMa-type dwarf nova V1212 Tauri
Jeremy Shears, Tom Krajci, Enrique de Miguel +6
We report CCD photometry of the superoutburst of the dwarf nova V1212 Tau obtained during 2011 January and February. The outburst amplitude was at least 6 magnitudes and it lasted…

Superhumps and grazing eclipses in the dwarf nova BG Arietis
Jeremy Shears, David Boyd, Tut Campbell +7
We report unfiltered photometry of BG Arietis (= SDSS J015151.87+140047.2) in 2009 and 2010 which shows the presence of superhumps with peak-to-peak amplitude of up to 0.36 magnitu…
Survey of Period Variations of Superhumps in SU UMa-Type Dwarf Novae. III: The Third Year (2010--2011)
Taichi Kato, Hiroyuki Maehara, Ian Miller +75
Continuing the project described by Kato et al. (2009, PASJ 61, S395, arXiv:0905.1757), we collected times of superhump maxima for 51 SU UMa-type dwarf novae mainly observed during…

Superhumps and post-outburst rebrightening episodes in the AM CVn star SDSS J012940.05+384210.4
Jeremy Shears, Steve Brady, Robert Koff +2
We report unfiltered photometry of the first confirmed outburst of the AM CVn system SDSS J012940.05+384210.4 during 2009 December. At its brightest the star was magnitude 14.5, 5.…
The orbital period of the eclipsing dwarf nova SDSS J081610.84+453010.2
Jeremy Shears, Steve Brady, Tut Campbell +6
We present time resolved photometry of the cataclysmic variable SDSS J081610.84+453010.2 and have established for the first time that it is an eclipsing dwarf nova. We observed an…
