Faint NEOs List

Follow-up of very faint targets, magnitude 21-25, in urgent need of observations

This page reports a list of faint one-opposition Near-Earth Objects (NEOs) in urgent need of observations. This site is very similar to the Priority List (PL), but it works complementary to the PL.

The targets for this service are those NEOs listed as URGENT or NECESSARY in the PL that do not meet the requirements of visibility of the PL any longer. As soon as the reach their "End of Visibility" status in the PL, they are immediately transferred into this page. We hope that observers with bigger facilities could follow-up them again before they disappear completely.

Objects brighter than magnitude 25.0 V and at least 30 degrees of elongation from the sun are eligible for this list according to this PLOT. This service is updated on a daily basis using data coming from the Minor Planet Center and the NEODyS databases.

Each category is represented by an abbreviation and the background color in the first column as indicated. For more information read the "Explanation of Symbols".
