Abstract	SN 1978K in the barred spiral galaxy NGC 1313 is a remarkable supernova. It is arare Type IIn that remains bright at X-ray through radio wavelengths over 30years after its explosion. Our ongoing multiwavelength observations probe thedense medium that was ejected by the progenitor star, possibly a Luminous BlueVariable. Our previous XMM-Newton studies discovered the X-ray emission has beencoming from two shocks in regions that may have a large abundance of helium.While the radio flux has been dropping, the X-ray and UV/optical fluxes haveremained surprisingly constant. Here we request a 100 ksec observation tocontinue the detailed spectral evolution study. As secondary science, we willobtain data on the ULXs X-1 and X-2, and the other luminous sources in NGC 1313.

Mission Description	The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
