We propose co-ordinated broadband monitoring of the ultraluminous X-ray sources (ULXs) in the nearby spiral galaxy NGC 1313. We request 10 pointings of 10 kseceach, distributed over a period of 6 weeks, with XMM-Newton EPIC pn as theprimary science instrument. These will be co-ordinated with simultaneousground-based observations. The science goals of our program are to investigatethe multiwavelength spectra and the short- and long-term variability of varioussources in NGC 1313, in particular the far off-center source X-2, which will beused to unveil the nature of ULXs. As a by-product of our study, we will provideadditional data to the on-going monitoring of SN 1978K.

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.
