comments:

• Strange pattern of emittance in B1 V at injection

• 40% BLM threshold at start of ramp, lifetime >100 h during ramp, and ~20h min lifetime when going into collision

• Wrong lumi provived by LHCb causing a runaway of levelling until inhibited by 30%/dump on IR8 BLMs

• SPS switched off TI2/TI8 and clear effect in IP2/8 luminosity

• 7 h of L-levelling

• Instability in B2 then in B1 following the longitudinal BU (just before switching on the wires)

• MKB B2 fault induced the dump
