The beam went three times around the LHC ring: see CMS’s e-commentary and CERN’s twitter. This is the milestone that was a big media event last year (September 10, 2008).
Update: now it’s 500 times around the ring (about 0.05 seconds). Last year’s record was about 9 minutes of continuous beam.
Update: up to 9 seconds, 30 seconds (50k events seen by CMS)…
Update: and now a beam in the other direction has made a full orbit. (All you gotta do is smack ’em together!)
Update (Nov 21): on Saturday, we got hours of stable beam (single beams, not colliding). This has never been done before with the LHC: from here on, it’s all new territory. Now I’ve got to get to work on the offline data, which should be great for detector alignment…

for orbits must study some equations

also for orbit equations are implies some equations of Kepler observed prof dr mircea orasanu and prof drd horia orasanu and followed

also for orbit equations are implies some equations of Kepler observed prof dr mircea orasanu and prof drd horia orasanu and followed that thus are obtained important results
