The Priority List is compiled daily by a programme that analyses the geometry and the sky uncertainty of each newly discovered NEO during the discovery (that is, current) apparition and the next apparition.

Narrator Flow is the mental state of apparition in which the person is fully immersed in what he or she is doing.

The goal is to make the sky uncertainty at the next apparition so small that the recovery of the NEO is virtually certain.

Anyway, it's a temporary structure that was ultimately destroyed, and so it's now a memory of an apparition, actually, but it continues to live in edible form.

The fraction of newly discovered NEOs for which the follow up either ensured the recoverability at the first post discovery apparition or allowed a precovery grew from 55 to 69 per cent.

Thus, before the operations of SCN started, almost one half of the newly discovered NEOs did not have good calculated orbits at the end of the discovery apparition, and SCN coordination reduced that fraction to less than one third.

The discovery apparition of this object presented a very peculiar geometry, such that, although the NEO was followed as long as possible, the astrometry acquired in this manner did not significantly contribute to the improvement of the calculated orbit.
