comments:

• First fill with 1800b

• Betatronic losses in first minute of ramp visible only in B1 this time, with peak of ~3 kW (nothing worrisome but still to be understood).

• Very large losses due to degraded vacuum (i.e. ecloud) at MKI, but also on XRPs in IR5. TCT.8 and TCL.6R5 in warning (>40% thl) until FT correction applied.

• Significant activity at MKI.8 with very frequent fast losses with UFOs signature

• Emittance blow-up especially on B2H with what looks to be a beam beam long range pattern
