The celebration will take place in the CERN Main Auditorium on the morning of 12 March 2019.

It is a free event, by invitation only, that will be webcast. You can already start planning your Web@30 viewing party: a unique opportunity to reach out to and further extend your scientific and social community by inviting guests to watch the event (live or recorded, based on your time zone and constraints) and follow up with a discussion. 


You can watch the live webcast or join a Viewing Party. 

For those who will be watching later in the day, the recording will be available immediately after the event finishes at 10:00am on the CERN Youtube channel at
