After coming home for dinner, no one on watch, so took it. Monitor was not running, so started it .... after ~10min things started, but monitor stopped itself, tried to restart, but it stopped again. The 'client_abort_acq' did not work, so stopped or_scheduler. Then tried to close the hatch and dome ... the hatch closed, but when the upper hatch closed I could see the lower hatch was not closed properly, despite Astelos reporting it closed ... so opened the uper/lower hatces agin... then the telescope slewed to a new objece (despite the monitor was not running!): ... then I closed the lower and uppper hatch, parked the telescope ... during which the 'both-limits-active' ocurred.. and then the telescope powered off.... Not sure what all the reasons for this are, but guessing perhaps the new(?) monitor. |

PROBLEM is gone/solved -- PERHAPS there were no objects available for the first ~30min ... seem ok now. Tried to abort or_req 93185 ... as that was in the queue, but only for execution after midnight. Other time critical ORs are inserted for after 22:00 UT, perhaps that is affecting something ?
