We report on the photometry of SN2006el, a supernova spectroscopically determined to be a type IIb. SN2006el is unique in that out of the roughly 6000 supernovae known to date, it is one of only a handful to be observed within 24 hours of its initial explosion. We were therefore able to study its early evolution and find evidence for a blue excess for t < 3 days. This blue excess caused by the light from the shock breakout allowed us, in conjunction with theoretical models, to determine the radius of the exploding star and find evidence for a compact progenitor star. This leads us to believe that SN2006el should in fact be classified as a type cIIb.
