### OBSDATE ### 20140713 ### LOGDATE ### 140714 ### OBSERVERS ### KWD (Stromlo) and YK (via Skype) ### WEATHER ### Clear with low humidity (45% SUSI, 40% ATCA) and low wind at start of night; increasing wind (~10km/hr), humidity, and intermittent cloud coverage beginning at 8:00 PM until close near midnight. ### LOCATION ### Other ### PROGRAM ### Nearby B-star multiplicity survey (KWD) ### SIDEROSTATS ### n3 s1 s2 ### TARGETS ### (with N3 + S1) HR 4853 - bright fringe-finding test ### QUALITY ### Quite bad (no/almost no useful data ### PROBLEMS ### N3 and S1 seem to work well, although worsening clouds during the evening prevented finding fringes on any survey stars. N3 seems to have a false indication of the south periscope being "IN", or is possibly stuck -- the status remains "IN" despite issuing "sout" commands in the sidcon window or parking using taskmaster. Used the "op s" command to override upon shutting down, following the wiki. Tested S2 to understand its perpetual slewing status and actual motion by watching (and screen capturing) the vidcon: when the status is "slewing" but the elevation value on the display is stuck, S2 is completely stationary on the vidcon. When the elevation value on the sidcon display changes slowly, S2 can be seen to move very, very slowly (e.g. 20 degrees in 1 hour) on the vidcon -- so we know the movement on the display is associated with real movement on the camera.
