Nice and clear skies
06:53:22Some clouds passed by attenuating for a few records45530EG
07:40:54chaning to daystar 82460EG
07:42:44Running with daystar1EG

02:15:49Removing the daystar prior to daytime path work 1EG
02:18:51Daystar removed to get nigthtime path reference counts.0EG
02:22:11counts at 30km79380EG
02:25:03Coiunts at 30km, turning on the lights to remove the iris79520EG
as I think the counts are low. want to verify that the iris
is not to blame
02:29:03counts at 30km, looks like the iris is to blame!122990EG
02:30:55pushed the choppe alt up by 30us0EG
02:37:47reinstalled the iris and converged0EG
02:42:46Counts at 30km 95600EG
02:43:36going the open the iris just a "tad"0EG
02:45:03done opening0EG
02:49:16Counts at 30km now ~11000110000EG
02:49:45Starting work on the daytime path0EG
02:51:18Turning seeding of the laser on.0EG
03:06:58Clouds moved in so work on the daytime path is out for the0EG
moment.
