    I just pulled the latest elsets from SpaceTrack and the objects you
    were missing were all present in the database and their elsets were at
    most 4 days old.
    The command I use is the following; you can paste it into your browser
    but may have to log into SpaceTrack on a different tab first.
    This will download the latest three line elements for each object
    which has a value for the epoch that is at most 30 days old.
