Night Assistant:

Also Present: 
Chris Smith, Ann Elliott
Problems: 
Seeing was very good for part of the night, (0.8-1.3) but poor tracking/guiding didn’t allow us to take advantage since many of the remaining targets are north. Poorer seeing at end of the night. A few SISPI problems tonight. 1 FCM error in community time. ‘No readout’ problem again after 155031 , pressed yellow Stop to start transfer. 155064 in strange exposure state where both exposure timers showed 30s count down then repeated 30s again and again. Killed with Yellow stop and readout. (need to check image)
Comments: 
Data were taken for 5 SV programs: Shibuya 3006: 154959-965 Fields z5-7 guiding marginal for all Cenko 3003: 154984- 5007, 155009- 032 Epoch 3 of Fields Eri06,08 , some guiding problems Bertin 3001: 154967-980 Hyades -3, marginal guiding Rest 3014: 155037-045 first 2 priority fields in g,r 100s, with pointing check before each Ytest 3004: Abell 3128 To replace Shibuya's change, 12 240s exposures with Y filter.

Can this be pulled from environment webpage?? Don't know what seeing variability 0-1 is suppost to mean? Yes seeing was variable is this the difference between the average and the max deviation??
