Description XMM-Newton has revolutionized the study of X-ray sources in nearby galaxies such as NGC 1313, a barred spiral galaxy that is 3.7 Mpc away. This contains two ultraluminous X-ray sources, and SN 1978K, the first supernova remnant recognized from its X-ray flux. NGC 1313 is close enough that XMM-Newton can perform detailed simultaneous spectroscopic and timing studies of all of them. In Cycle 2, we were awarded time to perform 7 Priority A observations as the first stage in a long-term program of monitoring the known sources, searching for new transients, and determining the diffuse emission component. Here we will continue this campaign by performing 4 more pointings of 10 ksec to study the sources on time scales ranging from seconds to months.

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.
