SS Cygni Outburst Predictors and Long Term Quasi-periodic Behavior

We report null results on a 2 year photometric search for outburst predictors in SS Cyg. Observations in JohnsonVand CousinsIwere obtained almost daily for multiple hours per night for two observing seasons. The accumulated data are put through various statistical and visual analysis techniques, but...

Zusammenfassung:We report null results on a 2 year photometric search for outburst predictors in SS Cyg. Observations in JohnsonVand CousinsIwere obtained almost daily for multiple hours per night for two observing seasons. The accumulated data are put through various statistical and visual analysis techniques, but we fail to detect any outburst predictors. However, analysis of 102 years of AAVSO archival visual data has led to the detection of a correlation between a long term quasi-periodic feature at around 10002000 days in length and an increase in outburst rate.
