L10706023:51:00Start of experiment29690EG
L10706023:51:15Starting out with Daystar to see if the system is operating28920EG
within normal parameters
L10706023:54:23Note, the receiver box is open.29500EG
L10706023:55:04SZA=82.0 S=2900 N=5528620EG
L10706000:04:45NLC detection at 85km. looks like I'm going to have to 29010EG
wait for another time to do the etalon tweeking
L10706000:07:09The R eq backscatter is arround 65km read using 192m bins29430EG
and 10 .
L10706000:25:17NLC getting stronger27690EG
L10706000:48:18NLC accending and getting thinner and weaker28240EG
L10706001:27:47Must be some haze or thin clouds in the way now, counts are25680EG
slightly down and the noise sligthly up
L10706001:49:37NLC still present23610EG
L10706002:28:12What a layer!!!!!!!24260EG
L10707002:29:31Incremented24260EG
L10707005:03:01Incremented24960EG
L10707105:04:09The layer has been visible troughout, getting broader now25530EG
and is no longer decending.
L10707105:41:46looks like the layer is fading, still present though.25700EG
L10707105:51:41Layer still arround, SZA=86.5 some haze, S=2600 N=3627210EG
L10707106:37:08Layer gone, well......if one is creative on might state that 27430EG
there is a layer still.
