| Description | We propose to perform spectral and timing measurements of the ultrasoft narrow- line quasar NAB 0205+024 with XMM. NAB 0205+024 is an extension of the class of ultrasoft narrow-line Seyfert 1 galaxies towards higher luminosities. The proposed observations are expected to build upon our guaranteed time observa- tions on NLS1. XMM spectra will allow (1) precision fitting of the soft X-ray excess and hard X-ray power law, (2) study of broad and ionized iron K line emission, (3) study of ionized gas along the line of sight, and (4) measure- ments of the Compton reflection continuum. XMM light curves will allow (1) studies of X-ray variability, (2) power spectrum analyses, (3) measurements of spectral variability. |

| 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. |
