| L20090127_000 | 04:08:07 | Trying to improve Rayleigh return | 2 | 0 | cp |
| L20090127_000 | 04:22:48 | That helped | 147 | 0 | cp |
| L20090127_000 | 04:23:37 | Nothing on the Raman channel | | 0 | cp |
| L20090127_000 | 04:25:43 | Powering up the PMT helped ! | 143 | 0 | cp |
| L20090127_000 | 04:31:08 | Tried to optimize HW pltes and apertures to get an improved profile | 162 | 0 | cp |
| L20090127_000 | 04:37:43 | Was not satified with profile, so did some adjustment. | | 0 | cp |
| L20090127_000 | 04:51:14 | Difficult to improve. Conditions outside perfect. | | 0 | cp |
| L20090127_000 | 05:06:31 | Lost a lot of signal. Lowering the chopper revealed a spike | | 0 | cp |
| | in the profile at low alt. indicating a haze layer. | | | |
| | Difficult to observe outside. | | | |
| L20090127_000 | 05:07:40 | But cannot improve signal because of this haze layer. | 56 | 0 | cp |
| L20090127_000 | 05:09:22 | Using binoculars it is possible to see the spot at the end of the | | 0 | cp |
| | LASER beam outside. | | | |
| L20090127_000 | 05:10:03 | Too bad, because something interesting is going on in the profile at | | 0 | cp |
| | approx. 65 km alt. | 91 | | |
| L20090127_000 | 05:35:47 | Haze layer is getting more dense. Will wait for 10 mins. | | 0 | cp |
| L20090127_000 | 05:46:26 | Looks like I will have to give up daq. tonight. | | 0 | cp |
| L20090127_000 | 05:52:57 | Thats it. Will try again tomorrow. | | 0 | cp |
| L20090127_000 | 05:53:38 | End of experiment | | 0 | cp |
