1. 1 XID Programme n Imaging Programme: multiband optical/NIR imaging of XMM fields n Core programme: spectroscopic/archival identification of u1000 high b sources 0.5-4 keV > 10 -13 erg cm -2 s -1 u1000 high b sources 0.5-4 keV > 10 -14 erg cm -2 s -1 u1000 high b sources 0.5-4 keV > 10 -15 erg cm -2 s -1 u1000 low b sources 0.1-10 keV > 10 -14 erg cm -2 s -1

2. AXIS highlights n International Time Programme at La Palma: ~90 observing nights Apr 2000 to Apr 2002 n ~20% of time used Mostly as expected: Broad line AGN at high b Active Coronae at low b But also: A BAL QSO A Be+White Dwarf? accreting binary Several NELGs
