L20020707_00021:16:02Start of experiment0EG
21:18:52Nice and clear skies 0EG
23:30:23ND81 has failed during warmup. No longer accepting ext trig.0EG
01:34:29Some slight cirrus creeping in.0EG
02:53:29Rayleigh Convergence mirror adjusted0EG
02:54:15counts (at 30km)20100EG
03:46:34Working on getting the sodium laser on line0EG
03:51:49Startng to take sodium data1EG
04:10:49Pushed the chopper atltitude up 1EG
04:13:46closing the operator cover on the SP laser bench1EG
04:27:49Must have bumped the Sodium convergence when I closed 19211EG
the lid, Reconverged the sodium.
L20020708_00619:22:12some cirrus clouds arround. A little denser than yesterday.1EG
20:19:39Sodium HG tweeked & counts (30km)20431EG
21:37:10Pausing data collection on the sodium channel while I check1EG
on things.0
22:37:39Cirrus clouds getting a bit more dense and covering a bigger0EG
portion of the skies.
L20020708_00823:01:38Started the sodium channel again. Gained 25mJ by using fresh11761EG
dye consentrat dye energy now 95mJ, incremented
L20020708_00923:05:24Counts (30km)15261EG
00:19:31Counts (30km)10421EG
00:32:17Sporadic sodium?1JJ
01:07:45Weak NLC throug the sirus clouds?1JJ

L20020708_00901:19:56Definitely NLC up there...1JJ
L20020709_00104:19:30Clouds getting thicker...1JJ
06:17:54Almost overcast now...1JJ
L20020709_00309:40:53Clouds moving in and out of beam1JJ
09:57:17Looks like clouds are getting worse. Going to shut down1JJ
