I used to have access to these, but it seems to be blocked. Is this a change of policy that "fans of LHC" can't look in the logbooks anymore? I had so much fun reading these...
Are you in the egroup invited-OP-elogbook-users? Access might have been lost in the move to the new logbook system. Might be worth sending an email.

Yes, I think I was. Let's give it a try.
I know a few people got kicked out because somebody started calling up all these people, so I can't blame them.
We'll see.

Now fingers crossed for Stable Beams @ 450 GeV on Friday - hopefully with less questionable collisions in IP8 (there was no reliable luminosity signal for IP8 on Wednesday, neither from the BRANs on machine side, nor from LHCb)

Yeah we're commissioning a brand new detector (without a hardware trigger) at LHCb. I guess the new lumi monitor (PLUME) isn't ready yet.

First 6.8 TeV stable beams currently scheduled for 5th July (along with a media event, I believe?).

Yes, there will surely be a big media event - by coincidence (or not quite...), the 10th anniversary of the Higgs discovery also falls into the same time period.

And the nominal bunches just made it up the ramp to 6.8 TeV!

Stable Beams at 450 GeV!

Also, this times all 4 IPs are really colliding, with LHCb measuring a luminosity signal for the first time with the all-renovated detector!

Test collisions with VDM cycle at 6.8 TeV (2 bunches / beam)

150th LHCC Meeting - OPEN Session
https://indico.cern.ch/event/1156732/

Longer than expected sector 23 training, issue with RF cryogenics and LHCb VELO readiness led to a shift of the schedule of 2.5 weeks: first “official” stable beams on July 5th

Injector beams are in good shape for LHC operation over the summer.
