The Annual Genral Meeting of ORSO will take place online in 14th-18th June 2021. The purpose of the meeting is to discuss topics of interest to the ORSO community. The program will consist of scientific and technical talks together with discussion forums for each of the working groups

Registration is now closed

If you have not registered and wish to attend the meeting, please contact Tom


A more detailed agenda is now available here using the european time zone.

Monday 14th June: Plenary Sessions

The pleanry sessions will introduce ORSO and summarise our activities since the last meeting. There will also be up to 8 scientific talks on subjects of interest to the ORSO community (speakers to be confirmed). Since the agenda is scheduled to try to cover all time zones, we acknowledge that it may be difficult to attend all these sessions. We will therefore record the plenary session and post the videos here after the meeting.

08:00-11:00 (UK), 09:00-12:00 (Europe), 04:00-07:00 (US East coast), 17:00-20:00 (Australia East coast):

Recordings of the talks are now uploaded. The saved chat is also available here
