| L20021113_000 | 01:25:16 | Start of experiment | | 0 | JT |
| 01:27:33 | Some thin cirrus, Rayleigh cnts from 40 km | 1450 | 0 | JT |
| 01:30:17 | Raised chopper from 25km to 35 km (Meteor trail in both?) | | 0 | JT |
| 01:34:22 | SR430 reset: Normal operations | | 0 | JT |
| 01:47:29 | Chopper function on Rayleigh seems broad | 1440 | 0 | JT |
| 02:04:35 | paused Rayleigh channel to block laser light and monitor bkgd signal | | 0 | JT |
| 02:18:10 | Pausing both systems to test iris clipping | | 0 | JT |
| 03:22:48 | Adjusted iris position along optical axis and closed | | 0 | JT |
| | iris to minimum opening - after some adjustments | | | |
| | found no change in signal while fully open and fully closed | | | |
| 03:24:26 | Chopper function: taking data on both systems, lamp bkgd only | | 0 | JT |
| | Chopper fully open at 32km (Na) and 40 km (Rayleigh) | | | |
| 03:34:11 | Paused data taking | | 0 | JT |
| 03:43:41 | Taking data with both systems functioning normally | | 0 | JT |
| | the Rayleigh chopping altitude has not changed | | | |
| | the Sodium chopping altitude was lowered by 45 microsec | | | |
| 04:15:23 | Raisng chopper from 40km to 50km (3411us to 3344us) | | 0 | EG |
| | impact on sodium was Na raised from 25km to 35km | | | |
| 04:46:34 | Changed chopper from 50km to 60km (3344us to 3277) | | 0 | EG |
| | sodium from 35km to 45km BOI 04:47:16 | | | |
| 05:18:20 | Changing chopper frim 60km to 70km (3277 to 3211) | | 0 | EG |
| | sodium from 45km to 55km BOI 05:18:59 | | | |
| 05:51:57 | Changed the chopper from 70km to 40km (3211 to 3411) | | 0 | EG |
| | Sodium from 55km to 25km. BOI 05:52:32 | | | |
