### OBSDATE ### 20140711 ### LOGDATE ### 140712 ### OBSERVERS ### KWD (Stromlo) and YK (via Skype) ### WEATHER ### Clear, little to no wind, moderate humidity (70% SUSI, 65% ATCA) increasing until close (102% SUSI, 89% ATCA) ### LOCATION ### Other ### PROGRAM ### Nearby B-star multiplicity survey (KWD) ### SIDEROSTATS ### n3 s1 s2 ### TARGETS ### (with N3 + S1) HR 8728 - bright fringe-finding test HR 5646 - B-star (first set possibly false fringes) HR 5695 - Calibrator (little to no data) ### QUALITY ### Quite bad (no/almost no useful data ### PROBLEMS ### 1) Loss of connections to peleas: Just before midnight, we lost the connections to peleas, automatically closing the pavo/acqlabjack/ldccon server windows and rendering everything else unresponsive ("K108 server is not open"). We could not ping rocs.physics.usyd.edu.au (but could ssh to it) and then got the following error message from peleas when trying to run k108: Sat Jul 12 00:15:08 2014 WARNING: Could not open serial port /dev/ttyC0. Sat Jul 12 00:15:08 2014 ERROR: Sorry, you cannot talk to /dev/ttyC0 It seems k108 cannot run because there is a device that it cannot read from or write to; considered rebooting peleas to reset this, but decided to wait to see what to do. It does seem that the roofs closed automatically (according to the logs). 2) S2 siderostat no longer indexes in elevation. Its status remains "moving" indefinitely, without changing the elevation value. We cycled power to the server twice, and tried to move it while it was attempting to index, but neither seemed to work. Maybe this would also need to be checked out in person? Switched to using N3 and S1, which worked fine until the server connections went down.
