We describe the Wise Observatory Optical Transient Search (WOOTS), a survey for supernovae (SNe) and other variable and transient objects in the fields of redshift 0.06-0.2 Abell galaxy clusters. We present the survey design and data-analysis procedures, and our object ... View more

Comparison with observations of various SNe II shows a similarity to the light curve of the Type IIb SN 2004ex obtained by the Caltech Core-Collapse Project (CCCP; Gal-Yam et al. 2006b, 2007), supporting the spectroscopic identification of this object as a Type IIb event. Unfiltered WOOTS photometry was calibrated onto the SDSS r-band zeropoint using SDSS photometry of nearby stars, while the light curves of SNe 1999em, 2004ex, and 2005gl were shifted temporally to match the spectroscopic age of SN 1999ay (Fig. 7) and arbitrarily scaled vertically for clarity.
