We report our attempts to locate the progenitor of the peculiar type Ic SN 2007gr in HST pre-explosion images of the host galaxy , NGC 1058 . Aligning adaptive optics Altair/NIRI imaging of SN 2007gr from the Gemini ( North ) Telescope with the pre-explosion HST WFPC2 images , we identify the SN position on the HST frames with an accuracy of 20mas . Although nothing is detected at the SN position we show that it lies on the edge of a bright source , 134 \pm 23 mas ( 6.9 pc ) from its nominal centre . Based on its luminosity we suggest that this object is possibly an unresolved , compact and coeval cluster and that the SN progenitor was a cluster member , although we note that model profile fitting favours a single bright star . We find two solutions for the age of this assumed cluster ; 7 \mp 0.5 Myrs and 20 - 30 Myrs , with turn-off masses of 28 \pm 4 M _ { \odot } and 12 - 9 M _ { \odot } respectively . Pre-explosion ground-based K -band images marginally favour the younger cluster age/higher turn-off mass . Assuming the SN progenitor was a cluster member , the turn-off mass provides the best estimate for its initial mass . More detailed observations , after the SN has faded , should determine if the progenitor was indeed part of a cluster , and if so allow an age estimate to within \sim 2 Myrs thereby favouring either a high mass single star or lower mass interacting binary progenitor .
