The engineering shutdown of the APO 3.5-meter will continue at least through the night of 24 September, i.e., scheduled science operations might resume on the night of 25 September. This further extension of the shutdown is required due to the necessity of an additional (3rd) aluminization of the new secondary and due to the discovery of a possible problem with the primary mirror's support system. A good coating of the new secondary has now been achieved. Further information on the latter topic is contained in a subsequent message. I am attempting to include the PIs and observers for affected programs in the distribution of this message, but the help of institutional schedulers and User Committee members in making sure that all the relevant people are informed would be appreciated.
