L319021:55:33Start of experiment0
L319021:56:47UPS! forgit to change records per scan to 600 on sodium0EG
L319022:00:32Going to adjust HWP0EG
L319022:06:23Done tweeking, no improvement. Incremnted60000EG
L319122:16:31Rayleigh Convergence mirror adjusted61020EG
L319122:57:19tweeked sodium convergence 3min ago76000EG
L319123:13:23!!!!!Sodium sporadic detection a few min ago @116km 77920EG
L319123:13:55tuned sodium from 589.162 back to 589.158 (it had drifted)0EG
L319123:19:22Sodium Convergence mirror adjusted77130EG
L319123:40:17layer at 112km, IS radar Es appeared at the same altitude81330EG
L319100:00:09Dye tuning drifting upwards tuned from 589.159 to 589.15880900EG
L319100:13:18Tuned dye from 589.158 nm to 589.156nm83000EG
NOTE Target wavelength on wavemeter should be 589.156
instead of 589.158nm
L319102:27:39Sodium Convergence had drifted. reconverged82050EG
L319102:31:21Forgot to note that the chopper altitude had to be lowered80820EG
to reaquire convergence....and of course Iforgot to change it
back. Done so now. Incremented
L320002:42:08I don't know if this is for real or not it apears that something0EG
very faint is showing up on the Rayleigh profile @95km
with hard subintegration at 192m bin width and 10 profile
integration. looks like it could be the start of some layer
L320002:45:17Sodium Convergence mirror adjusted83300EG
L320004:02:17End of experiment84610EG
