We propose to take a deep [O II] image of SN 1987A and its nebula with STIS.Supernova 1987A is a once-in-a-lifetime event that enhances our understandingof the late stages of the stellar evolution, the supernova explosionmechanism, and the interaction of the explosion with the circumstellar medium.Studying the inner ring not only also tells us about the pre-explosion stellarevolution, but also the blast of radiation emitted by the supernova thationized the ring during the explosion. By comparing our results with existingHST images, we can also look for temporal and spatial variations of thecircumstellar system, which is particularly interesting because of itsintensifying interaction with the expanding debris.
