The brightest comparison is near maximum threshold and we have had to defocus slightly more a couple of times. No obvious blip in the light curves. Conditions still excellent. I had a look at the defocussed image of the comparison and could see no sign of problems. No obvious problems in reduced light curve either. 125 mins in, we are struggling to track very close to the zenith. Watch data quality here, there is distinct bump that I think is down to the transit passage, not anything real. We have seen similar effects around zenith, and this was especially close. Finsished at high airmass. Nice looking transit.
run014       POWON   run014   The last run just hung for no reason; took a while to realise as this is very unusual.

run008       POWON   run008   Re-booted data PC to see if we could improve network speed; apparently not.
