L722022:05:43Start of experiment9490EG
L722022:10:33SZA=75.4, dye energy 90mJ and the sodium layer is visible16120EG
L722023:19:14Thin, week NLC R.eq~65km17530EG
L722000:17:07counts19960EG
System Note: I noted that the beam shape seen on the
Sodium window on top of the chimey was not a full circle!
The first (old) roof is causing vignetting of the beam!
L722000:41:14Counts19840EG
L722001:08:21!!!! Huge sporadic Sodium0EG
L722001:22:42Checked the wavemeter it's reading 589.158nm21030EG
L722001:51:03Wavemeter reading uncanged20750EG
L722002:21:37A weaker second layer has apperaed above the first one20110EG
This is agrees with the Es structure seen on the IS radar
L722002:31:39Wavemeter still showing 589.158nm20400EG
L722003:20:26The two layers have fused into one16880EG
L722003:20:39I don't dare run with this single file any more, incremented16880EG
L723003:21:42Counts16530EG
L723003:43:01Wavemeter still dead on 589.158nm16100EG
