                         • horizontal ac dipole wasn’t firing
                           due to technical glitches
                         • vertically, the maximum coherent
                           we Got without lossing beam is 0.2mm
                           in the middle of arcs and 1mm at Q3
                         • The preliminary measurement shows
                            the vertical beta* at IP8 is about
                            30% larger than IP6

  •Studies after maintenance if intensity/polarization too low
   for physics
  •Make-up some hours for APEX next week
