La Silla good nights of year 2008. (a) The percentage of nights with more than 6 hours of opening for REM dome: it may be considered very close to good weather nights in La Silla. (b) The shutter-open time percentage for REM cameras: red portions are the Observing Blocks ending with some error status which are to be repeated. No overheads have been included in this plot. The month of August included a two-week maintenance mission which makes those data inconsistent.
