Here's an update on the LHC at CERN (Note: this entry has been updated twice today, in light of further clarification of what the timings actually relate to.)
According to the CERN website a beam completed it's first full circuit around the LHC at 10:28am CET (the website doesn't state the time zone, but I confirmed it with the press office by telephone. Note that 10:28am is given in the press release, but 10:25am is stated by CERN on their Twitter page updates). The 'first beam' moment was at 9:30am CET, so the previous chart stands, and this chart below is a secondary chart at best.
The second beam to complete a full circuit started at 1:55pm CET and completed its lap at 3:02pm CET, according to the CERN website: "15:02, that's it. Second beam all the way round and the LHC is up and running."
The inauguration of the LHC is due to take place on 21st October 2008 at 3pm CET.
