Program
In order to attend the O-MESS, please subscribe to our mailing list. We will send out the Zoom invitation the day before each O-MESS.
Below you can find the program of our meetings. The O-MESS will take place bi-weekly on alternate Tuesday and Wednesdays. The first O-MESS will take place at 17:00 Central European Summer Time (CEST), and the following ones at 17:00 Central European Time (CET) to enable the largest possible global participation. In exceptional cases when e.g. these times are not convenient for the schedule speaker, we might reschedule the seminar to another time. Please check this page regularly for updates.
At what time will O-MESS take place in my city?
This is a good question! Not all countries switch to daylight saving time at the same time, and others do not at all. You can use e.g. this Time Zone Converter to find out at what local time O-MESS will take place. In the e-mail with the Zoom invitation, which will be sent out the day before each O-MESS, we will also include local times for major cities to help avoiding confusion.
