| Description | Between 2007 and 2020, our XMM-Newton monitoring of SN1987A yielded EPIC and RGS spectra of unprecedented quality. The fluxes and broadening of the numerous emission lines provide information on the evolution of the X-ray emitting plasma and its dynamics. The soft X-ray light curve has displayed a steady flux decline from 2014 decreasing18% of its peak value by 2020. To further monitor the evolution of the X-ray flux and to follow the expected turnover we propose to continue our monitoring.This will allow us to further study the time evolution of the shock conditions and abundance profiles. At high energies EPIC-pn can monitor the hard band continuum and help to clarify the extremely low observed Fe abundance by following the evolution of the detected Fe-K line |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
