Observing Sessions

The EVN regularly observes during pre-scheduled observing sessions every year. EVN observations may be conducted using disk recording (standard EVN) or in real-time (e-VLBI).

Scheduled standard EVN sessions

Standard EVN observations (disk recording) are spread across three different sessions during the year. Each session covers approximately 21 days and the observing wavelengths are planned according to proposal pressure. The block schedule for EVN observations is public a few weeks before the observations (latest block schedule).

Year	Session	Dates (Day/Month)
2020	Session 1	20 Feb - 12 Mar
2020	Session 2	28 May - 18 Jun
2020	Session 3	15 Oct - 05 Nov
2021	Session 1	25 Feb - 18 Mar
2021	Session 2	27 May - 17 June
2021	Session 3	21 Oct - 11 Nov

Scheduled e-VLBI sessions

Ten e-VLBI sessions are scheduled every year, with sessions lasting 24 hours. Each session observes at only one frequency, which is decided based on proposal pressure. The schedule for the latest e-VLBI run can be found here.

Note the time reserved for science projects is 13:00-13:00 UTC.
