L718022:34:40NLC detection15940EG
L718001:06:39rayleigh SR430 frozen reebooted and incremented file15910EG
L719001:41:35clouds0EG
L719009:13:16Incremented17040EG
L719109:13:46very nice NLC!17040EG
L719110:02:45Some pathces of clouds have moved in13750EG
L719110:06:28NLC is no longer visible16160EG
L719110:37:03Incremented, it looks as the clouds will stay a while12760EG
L719211:40:43Clouds have gone, booming NLC!0EG
L719213:16:46NLC no longer visible, scattered cirrus around16420EG
L719213:49:32Clouds are killing the signal for the moment21550EG
L719214:24:15Incremented, aquiring cirrus height data on both systems01EG
L719314:27:26First bang on Rayleigh channel is 33.64microseconds1EG
L719314:27:27first bang on sodium channel is 33.28microseconds1EG
Runnign with reduced PMT HV
L719315:01:07Conveged both systems to the first bang1EG
there is total agreement on the altitudes +/- 1 Bin
L719315:02:59both systems indicate first bang is 28.8usec1EG
The structure seen on both channels differes to much
to be able to use this. We have to wait for higher clouds
