SN 2009ib was a Type II-P supernova (SN) that exploded in NGC 1559. We collected extended observational datasets of this SN, which was published in Takáts et al. (2015). Our study included analysis of archival HST images of the host galaxy, allowing us to search for the progenitor of the SN. These images, however, are not particularly deep therefore our study resulted in several open questions. In order to answer these questions, we obtained new, deeper post-explosion images in October 2015 with HST. In my talk I'll present the results of our on-going analysis of both the pre- and the post-explosion HST images and discuss the implications for the progenitor and the environment of SN 2009ib.
