We propose to make a 120 ks XMM-Newton observation coordinated with NuSTAR ofthe little known NLS1, IGR J19378-0617, in order to probe a broad range ofvariability timescales in this extremely bright, low-mass source. It has beenobserved with XMM-Newton for only 12 ks and is clearly detected in the BAT70-month catalog. Despite its short exposure, this source shows severalinteresting features that require further exploration, including a low-frequencycontinuum lag, even hints of high-frequency reverberation, and a low-ionizationwarm absorber in the RGS. It is also a hard X-ray source that will clearly bedetected by NuSTAR. Given its strong variability and high count rate, it haspotential to reveal time lags above 10 keV.

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.
