Comparison weak in u. Good conditions, seeing 1", clear. Moving into twilight towards the end of the run. End of night. Very good night, no problems.

Looking into lower shutter (broken) at the start so counts rise in first 5 minutes. Focussed after 7 mins. Seeing = 1". Clear. Some pickup noise in u, but seemed to fade after a few minutes. Bright comparison OK for u but too bright for g and r. Use sum of fainter comparisons for g and r. 2 hours in, conditions still good. Clear, seeing 0.9". 3 hours in: conditions steady. Guider moved stars a few pixels 225 mins in. Corrected 20 mins later. 6 hours in: conditions the same as ever. 8 hours 20 mins: nearing end as elevation sinks to 25.
