L20040527_00022:56:54Start of experiment1530EG
23:15:48Thin miky haza above,1530EG
23:16:06Turning on the Sodium system1530EG
23:31:35Crash on the sodium SR4301570EG
23:36:54Started again1440
23:52:07Corrected the waveplates after the PC crash1440
L20040527_00100:15:41Sodium SR430 crashed again - recovered1630
00:16:58Incremented filename1720
00:53:51Raised the sodium chopper1760
01:45:54Removing daystar0
L20040528_00201:48:01Running again without the daystar, incremented1
L20040528_00201:49:36Still quite hazy cirrus all around10411
L20040528_00201:51:30Converged Rayleigh10301
L20040528_00203:12:33looks like there is a sporadic sodium layer forming11421
L20040528_00203:17:47Verifying waveplate positions12021
L20040528_00203:27:51Done optimizing waveplates, converged rayleigh12241
L20040528_00203:28:55!ups, looks like I have bumped something ono the sodium1
channel ,
L20040528_00203:38:42Yes! I had bumped the last folding mirror in the soidium 11951
channel, corrected
L20040528_00203:40:13Clouds moving in12081
L20040528_00203:56:31Thick clouds blocking the beam now91
