Start with LBC 
02:35 start NGC 6946 seeing 0.8 
03:10  end 
03:11 switch to MODS 
03:42 move to flux std BD+33d2642
clouds moving in from west
initial problems with acq on left side 
04:05 start BD+33d2642  there may be clouds during this exposure 
04:19 end
04:20 moving to flux std Feige 110 
04:29 start Feige 110 seeing 0.8 (note aborted MODS1 blue, red only, prismin
script) 
04:43 end
04:46 moving to OSU_redLSBGs G156, Note able to easily see G156 with 2m acq 
05:05 start G156 2 x 1800s, seeing 0.8- 1.0 posible some thin clouds at start of 1st exp.
06:08 end 
06:10 moving to UM analog M33-8
06:25 start M33-8, 4 x 900s, seeing 0.8 -1.0 sky clear
07:34 end
07:35 moving to OSU_redLSBGs G191
07:54 start G191, 3 x 1800s, seeing 0.8 -1.0 arcsec, clear  
09:30 end  
09:34 moving to G196 easy to see target 
09:46 start G196, 2 x 1800s, seeing 0.9, clear 
10:50 end
 
Note next two flux stds are observed with MODS1 red only for program OSU_BDVar
10:54 moving to g191b2b 
11:07 start g191b2b
11:15 end
11:15 moving to gd71
11:20 start gd71
