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…
The orbital and superhump periods of the deeply eclipsing dwarf nova SDSS J122740.83+513925.9
Jeremy Shears, Steve Brady, Jerry Foote +2
During June 2007 the first confirmed superoutburst of the eclipsing dwarf nova SDSS J122740.83+513925.9 was observed using CCD photometry. The outburst amplitude was at least 4.7 m…
Photometry and astrometry of SS Leo Minoris during the 2006 October superoutburst
Jeremy Shears, David Boyd, Tom Krajci +3
We report unfiltered CCD observations of the first confirmed superoutburst of the SU UMa-type dwarf nova SS LMi in October 2006. From a quiescent magnitude of around 21.7 it rose t…
Superhump periods in the UGSU-type dwarf nova SDSSp J082409.73+493124.4
David Boyd, Jeremy Shears, Robert Koff
We present observations and analysis of the first reported superoutburst of the dwarf nova SDSSp J082409.73+493124.4 during February/March 2007. From a maximum observed magnitude o…
Observations of the first confirmed superoutburst of SDSS J080434.20+510349.2 in 2006 March
Jeremy Shears, Geir Klingenberg, Pierre de Ponthiere
During 2006 March the first confirmed superoutburst of the dwarf nova SDSS J080434.20+510349.2 was observed using unfiltered CCD photometry. Time-series photometry revealed superhu…
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…
Analysis of the first confirmed superoutburst of V337 Cygni in 2006 May
David Boyd, Tom Krajci, Jeremy Shears +1
During 2006 May the first confirmed superoutburst of the dwarf nova V337 Cygni was observed using unfiltered CCD photometry. The outburst reached a peak magnitude of 15.2 on May 22…
HR Lyrae (Nova Lyr 1919): from outburst to active quiescence
Jeremy Shears, Gary Poyner
Nova Lyrae was discovered at the Harvard College Observatory on 1919 December 6 at magnitude 6.5. We present a lightcurve for this nova based on published and archival observations…
