| Abstract | A previous relatively short (24~ks) XMM-Newton observation of ESO~323--G77revealed a remarkably rich X--ray spectrum both in absorption and emission.Despite its Seyfert~1 nature, the X--ray spectrum is highly absorbed andresembles that of a typical Compton--thin Seyfert~2 galaxy. Two ionizedabsorbers/emitters imprinting a series of blueshifted absorption and emissionlines. The robust detection of a relativistic Fe K line with relatively largeequivalent width (200~eV) makes this source even more interesting. ESO~323--G81is also present in the field. A broad excess is detected in the 6--7~keV regionpossibly revealing the presence of a braod Fe K line in this object. We proposea 130~ks observation to study in details the properties of both sources. |

| 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. |
