Russet and I tried resolving the issue but nothing worked so I set the filter by hand and we went from there. PR submitted. gcam hung after I did the focus sweep at midnight. I just had the restart the nubs to recover. I saw a couple of fiducial too large errors tonight in Az. The first one was when I was slewing to a focus star at the start of the 2nd program. I chalked it up to the telescope tracking a single object for several hours during first half. The second instance was at the end of the night after a long slew and near the park postion. ------- FAILURE LOG ------- FAILURE MODE TIME PROG INSTR TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- JH07 A I/H 17:16 17:45 Could not home ARCTIC filter.
