    Hi all,

    Very sad news. Tonight we could not start
    CISCO observations due to a filter wheel
    problem. Kentaro Motohara went up and tried
    to fix it, but could not, since the problem
    is rather inside the dewar. It is impossible
    to fix the problem in short time scale.

    So very unfortunately we expect no more CISCO
    observations in this run.

    We start discussing compensation time, but
    we don't expect much in short time scale,
    since the telescope schedule is very tight
    till mid Dec. Only the possibility I was
    told is another Suprime-Cam night on Dec.6,
    though it is not still certain yet.

    Well, we have had various sorts of troubles
    for Subaru follow-up observations; a broken
    actuator, IR secondary mis-alignments, scattered
    lights, and filter wheel trouble of CISCO.

    Especially CISCO has been a very reliable
    instrument since SUBARU first light (Jan.1999).
    So we are really unlucky...
