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).
