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).

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.

Scheduled out-of-session observations

Scheduled out-of-session observations can be found via the following link.

JIVE keeps a public archive of previous block schedules for:

• EVN/Global VLBI sessions
• e-EVN sessions. 
• Out-of-session EVN/RadioAstron observations
