H-alpha and GALEX near-UV images are used to trace on-going and recent star formation (SF), while broad band B, R, J, K imaging is also analysed. Using pixel statistics we find that SNe~Ia show the lowest degree of association with H-alpha emission of all supernova types. It is also found that they do not trace near-UV emission. As the latter traces SF on timescales less than 100 Myr, this rules out any extreme '","authors_text":"F. F\\\"orster, J. D. Lyman, J. P. Anderson, M. Hamuy, P. A. James, S. Gonz\\'alez-Gait\\'an, S.
