The intention was to have the first half night with SofI, but after the first couple of observations the frames showed lots of electronics noise. This seems a well-known problem with SofI, but the quick-and-dirty workaround did not succeed. We thus switched right away to EFOSC.
The night was otherwise very good with good seeing and clear conditions.
