The 2008 February superoutburst of V452 Cas
Christopher Lloyd, Roger Pickard, Jeremy Shears +3
Observations of the 2008 February outburst of V452 Cas show that the profile, duration and magnitude at maximum were very similar to the previous superoutburst in 2007 September. L…
Outburst characteristics of the dwarf nova V452 Cassiopeiae
Jeremy Shears, Christopher Lloyd, David Boyd +3
V452 Cas was thought to have rare outbursts, but monitoring from 2005 to 2008 has shown that the outburst interval is about one month and is weakly periodic. Observations of seven…
The orbital period of the eclipsing dwarf nova CG Draconis
Jeremy Shears, David Boyd, Steve Brady +1
We have performed time resolved photometry on the dwarf nova CG Dra and have established for the first time that it is an eclipsing system. By measuring the times of the eclipses,…
Measuring the period of the delta Scuti variable U1425-01208594 in Cassiopeia
Jeremy Shears, David Boyd, Steve Brady +2
The variability of U1425-01208594 was recently discovered by Schmidtobreick et al, who suggested that it is a member of the delta Scuti family of pulsating stars. Photometry conduc…
Photometry of the dwarf nova AW Sagittae during the 2006 November superoutburst
Jeremy Shears, Roger Pickard, Tom Krajci +1
During 2006 November an outburst of the dwarf nova AW Sge was observed using CCD photometry. This revealed 0.25 magnitude superhumps confirming it to be a superoutburst, possibly o…

Alex Golovin, Aaron Price, Matthew Templeton +11
We present multicolor CCD photometry of ASAS 002511+1217.2 for first 55 days of 2004 outburst.
