Description 1E 161348-5055 is a point-like, radio-quiet X-ray source at the center of the 2000-years-old supernova remnant RCW103. Recent observations unveiled a unique phenomenology: (i) the source has a dramatic (factor 100) long-term flux variability with outbursts possibly recurrent on the few year time scale; (ii) its emission is strongly modulated with a puzzling 6.67 hour periodicity; (iii) no counterpart in the optical-infrared has been found yet. In view of the source variability, XRT onboard Swift is currently performing a monthly monitoring campaign. Here we ask for a new 75 ks XMM triggered observation to be performed if a new outburst will be detected. Studying the 6.67 hours periodicity in the high state regime will shed light on the nature of this puzzling source.

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.
