PERIOD 8th August 2015 - 24 August 2015 SHIFTERS Washington Carvalho, Alan Coleman, Aida Lopez, Foteini Oikonomou, Rodrigo Pelayo, Dmytro Ragozin, David Schmidt MAIN ISSUES - 5-8 Aug: LA not operated due to power line being down or unstable - 7,12 Aug: No data acquisition due to rain/snow all night - 11-24 Aug: LL Lidar crashed almost every night after a few minutes of data taking. On most nights, it was possible to restart it for a few more brief runs. - LA Lidar PC crashed during data acquisition and connection was impossible. Luckily, NAGIOS took over and automatically closed down Lidar and cover. - 22-24 Aug: LA lidar cover having problems the last three nights of the shift. Running Cover Open/Close would result in being told that the cover was both closed and open, respectively. The solution of running Emergency Stop, Emergency Reset, then powercycling the steering was found to work. EXTRA ACTIVITIES DURING THE SHIFT - RAMAN shots from 1:25am to 1:55am, closing the respective bays SHORT OVERVIEW OF DATA OBTAINED - Figure ... shows the rate of T3 events as a function GPS Second for the duration of the shift. - Figures ... show the zenith, energy, and Xmax distributions of selected events collected during the shift. We have used standard Offline FD and Hybrid reconstruction routines for the event distributions shown here. Fixed calibration constants and parametric models have been used for the description of the atmosphere in the Offline reconstruction. - Figures ... show the FD Event Browser display for events selected events with energy greater than 10^19.2 eV.
