Context : Supernova 1987A revealed that a blue supergiant ( BSG ) star can end its life as a core-collapse supernova ( SN ) .
SN 1987A and other similar objects exhibit properties that distinguish them from ordinary Type II Plateau ( IIP ) SNe , whose progenitors are believed to be red supergiants ( RSGs ) .
Similarities among 1987A-like events include a long rise to maximum , early luminosity fainter than that of normal Type IIP SNe , and radioactivity acting as the primary source powering the light curves .

Aims : We present and analyze two SNe monitored by the Carnegie Supernova Project that are reminiscent of SN 1987A .

Methods : Optical and near-infrared ( NIR ) light curves , and optical spectroscopy of SNe 2006V and 2006au are presented .
These observations are compared to those of SN 1987A , and are used to estimate properties of their progenitors .

Results : Both objects exhibit a slow rise to maximum and light curve evolution similar to that of SN 1987A .
At the earliest epochs , SN 2006au also displays an initial dip which we interpret as the signature of the adiabatic cooling phase that ensues shock break-out .
SNe 2006V and 2006au are both found to be bluer , hotter and brighter than SN 1987A .
Spectra of SNe 2006V and 2006au are similar to those of SN 1987A and other normal Type II objects , although both consistently exhibit expansion velocities higher than SN 1987A .
Semi-analytic models are fit to the UVOIR light curve of each object from which physical properties of the progenitors are estimated .
This yields ejecta mass estimates of M _ { ej } \approx 20 { \mathrm { M } _ { \odot } } , explosion energies of E \approx 2 - 3 \times 10 ^ { 51 } erg , and progenitor radii of R \approx 75 - 100 { \mathrm { R } _ { \odot } } for both SNe .

Conclusions : The progenitors of SNe 2006V and 2006au were most likely BSGs with a larger explosion energy as compared to that of SN 1987A .
