Abstract:                                ! Free format text (please update)
    We propose to use archived WFPC images of SN 1987A to
    investigate the structure and time--dependent evolution of the
    three rings surrounding the supernova. New software has
    recently become available to permit reduction and extensive
    analysis of the WFPC images which was extremely difficult or
    impossible before. We plan to subtract a Tiny--TIM generated
    PSF template from the images to remove the deleterious effects
    of two nearby bright stars, which should reveal detail of the
    three rings that was previously obscured. These new data can
    then be compared with the archived FOC data (already reduced
    and analyzed by Plait as part of the Supernova INtensive
    Study), and can also be compared to the post--refurbishment
    FOC and WFPC2 images, which are expected to be made public
    shortly. Except for the few post--refurbishment images, Plait
    is already in possession of all the images necessary, so no
    archive retrieval is needed.
