Mrk 1044 is one of the brightest super-Eddington NLS1s in X-rays, making it anideal laboratory to study the geometry of accretion disc. A large XMM-Newtonprogram has been conducted on it in AO17, with a major objective to study theshort timescale time-lag and covariance between OM UVW1 and X-rays. This studycan verify the puffed-up inner disc structure of a super-Eddington AGN. However,the 1st and 3rd orbits suffered from the failure of field acquisition, while the2nd orbit was severely affected by an anomalous drift of satellite pointing,causing complete loss of OM Fast-mode data. We propose to re-observe Mrk 1044 tocompensate for the data loss in the 2nd orbit, in order to obtain a continuousUVW1 fast-mode light curve to achieve the key objective of our large program.

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.
