It was a complicate job and design started only during week 32, which made impossible to complete the job on time. Advice from G Huster was received. A simple device was devised, but it has been discovered that one of the plates that support the F.P. is glued and cannot be dismounted. A new F.P. will be purchase from Garching IR group.

Responsible: L Aguila Deadline: end of February. CLOSED 96.10 T 96.04.01 CABLE(S) MAY BE CUT DURING TELESCOPE MOVEMENTS Action: This point was previously listed by mistake under the ESO 152 Telescope. According to the analysis from R Medina, the only solution is a radical cure, passing the cables trough the cable hole in the fork. For the amount of work involved, it is considered a project, for which the 2.2 Team will provide requirements. Responsible: M Maugis Deadline: TBD when Rolando is back from vacations. CLOSED 96.09 E.
