Weather: clear, but slightly hazy over the mountains

seeing 5 - 7 cm

NIRO crash... - restart cpu+server
W1 acquisition would not work - restart
E2 acquisition failure - restart
tip/tilt gui did not work - restart

       recording fringes at 500Hz/NONDEST/LONG ! -> aborted
       cancelling, bad align
       tip/tilt too exposed on check star (7 Sco) creates alignment problems
       need to realign niro

     seeing is bad, piston is worse...
     W1 got stuck during the data, got it back

     difficult to see fringes on the target
     rather low counts
realign niro
