Protocol for Negative Observations for Virtual Impactors¶
The VI Observations Protocol version 3.1 document delineates observational strategy requirements aimed at removing virtual impactors of unrecoverable near-Earth asteroids (NEAs) in the risk list, or NEAs with such great sky uncertainty that they would be difficult to cover with state-of-the-art telescopes.
This protocol resulted from collaboration among the following organizations:
- Minor Planet Center (MPC)
- JPL Center for Near Earth Object Studies (CNEOS)
- ESA NEO Coordination Centre
- SpaceDyS
