L980910022:15:26Start of experiment28680EG
L980910022:24:30looks like a healthy sodium layer27230EG
L980910022:24:49gonna adjust the Halfwaveplates27230EG
L980910022:44:25Done adjusting Incremented25060EG
L980910122:45:11forgot to change the Recs per scan on record one24640EG
L980910123:23:00Changing to setup 120940EG
L980910123:24:50resumed running with setup 120541EG
L980910123:26:45Rayleigh Convergence mirror adjusted20191EG
L980910100:07:30Rayleigh HG adjusted28101EG
L980910100:07:41Wavemeter has been stable on 589.158nm from startup28101EG
L980910203:20:18There seems to have been a dip in the sodium return28761EG
with a minimum just about an half hour ago
L980910203:22:13Just checked wavemeter, it's still stable on 589.158nm and 28851EG
the room temperature has been stable troughout the run
L980910304:15:30Sodium has grown a bit over the last 15 min.28051EG
L980910304:41:11total sodium counts have fallen again, it looks like it's only 28311EG
the top of the layer is varying
L980911006:10:03incremented filenumber, gonna see if I can max the sodium27661EG
L980911006:12:30Dye energy had fallen to 60mJ maxed to 65mJ26761EG
L980911006:15:20Sodium Convergence mirror adjusted27641EG
No visible effect , wavemeter dead on 589.158nm
L980911006:19:31End of experiment28431EG
