L991012222:57:29Counts39670EG
L991012200:14:28The sodium was tuned. beginning at 23:50UT at 589.018 54620EG
On the PC and stopped at maximum 589.013 00:14UT
L991012200:19:02Paused the sodium for a moment to tweek energy it 52330EG
was at 35mJ tweeked to 45mJ
L991012200:56:46Sodium Convergence mirror adjusted51040EG
L991012301:42:32Rayleigh HG adjusted49400EG
L991012302:44:44there is a peek on the sodium layer now. It may be a sporadic 0EG
layer! It probably started to appear around 1:14UT
L991012404:01:27Started tweeking the Sodium system, tuned from 589.01356470EG
to 589.019 on the PC to maximize sodium counts
L991012404:15:41done tweeking the sodium. The temperature drift changed the 0EG
tuning.

L991012711:24:06John said iris should be about 1 mm open, adjusted to that2772KR
L991012711:27:23That killed the SNR, adjusted to ~1.5 mm1972KR
