We use a sample of 45 core collapse supernovae detected with the Advanced Camera for Surveys on board the Hubble Space Telescope to derive the core collapse supernova rate in the redshift range 0.1 < z < 1.3. In redshift centered on < z > = 0.39, < z > = 0.73, and < z > = 1.11, we find rates of 3.00^+1.28_- 0.94+1.04^_- 0.57_, 7.39^+1.86_- 1.52_ ^+3.20_- 1.60_, and 9.57^+3.76_- 2.80+4.96^_- 2.80_, respectively, given in units of/yr M/pc3 10^–4 h ³₇₀. The rates have been corrected for host galaxy extinction, including supernovae missed in highly dust-enshrouded environments in infrared bright galaxies. The first errors are statistical while the second ones are the estimated systematic errors. We perform a detailed discussion of possible sources of systematic errors and note that these start to dominate over statistical errors at z > 0.5, emphasizing the need to better control the systematic effects. For example, a better understanding of the amount of dust extinction in the host galaxies and knowledge of the supernova luminosity function, in particular the fraction of faint M ≳ -15 supernovae, is needed to better constrain the rates. When comparing our results with the core collapse supernova rate based on the star formation rate, we find a good agreement, consistent with the supernova rate following the star formation rate, as expected.
