General Description

We propose to spectroscopically verify distant X-ray luminous clusters
 of galaxies. We right now submit 4 clusters found using VLT FORS2, and in run (a)
 we defined preimaging for sources observed using other telescopes.

Right now the canidates are:
XMMU J113227.7-343403
XMMU J123016.9+133904
XMMU J123121.6+175412
XMMU J153213.2-083701

Two more observations with available pre-imaging have been added:
XMMU J100721.6+125754
XMMU J124250.5+022745

The final mask for 3 OBs has been submitted (22. July 2008)
XMMU J221720.8+141754.6

Waiver Requests
