Great seeing. At ~03:30 echelle slitviewer seemed to be having trouble finding stars. No errors anywhere, everything *seemed* to be happy. Multple locations with bright stars produced the same slitviewer image. I suspected software problem at first. Restarted ecam, nubs, init - nothing. Looked in the instrument, nothing (like eyelids, tertiary, or the cal mirror) was blocking the light path. Switching to lamps with quartz on, sliviewer looked about the same. Called Bill. At this point we suspect the shutter is stuck. Could not fix in last hour remaining of the night.
