L222220:26:48Start of experiment0KR
L222220:43:40I can't get the wavemeter to tell me squat, despite the 1150KR
mJ of power, and there's no Na in the signal, so I'm tuning
totally by dead reckoning.
L222220:46:26In fact. I'm gonna change the recs per scan to 10 secs, since0KR
that won't bother anything any will speed up feedback.
L222221:29:52While I was attending to a crowbar, suddenly Na signal 0KR
appeared. I think it was tuning i did just before.
L222221:33:48I had found a note with Na tuning setpoint scribbled on it. 0KR
It had been way off that. Fine tuning.
L222321:46:50Finished tuning, set recs/scan back to 600, incremented file1KR
number. L2222 is complete rubbish.
L222321:52:45Also, in the course of finding Na layer, iris got fully opened.1KR
L222323:51:59Sodium Convergence mirror adjusted,turned wavemeter off1EG
L222323:59:24tuned -1pm1EG
L222300:00:51tuned -1pm1EG
L222300:05:01Stopped tuning1EG
L222300:08:29looks like a small soradic layer at 98km, fewer counts at peek1EG
than the peek of the sodim layer
L222300:49:34Thin low altitude cloud attenuating the beam1EG
L223002:15:14incremented, rayleigh laser running now2EG
L223002:48:49Sodium and rayleigh Convergence mirrosr adjusted2EG
L223002:54:51Sodium Convergence mirror adjusted49522EG
L223006:04:36I'm seeing fewer rayleigh counts than before, probably49522EG
