These objects are all known and identified as:
93320 20670/90057A
93321 21422/91042A
93322 39766/14029A
93323 23318/94066B
93324 37363/11005B

It turns out that as of today the SpaceTrack catalog is no longer
consistent in its TLE format. Some objects will have the NORAD catalog
number padded with preceding zeros, while objects will not. It appears
the TLE reading routine in sattools does not work with the latter
format, resulting in very few objects being read. Hence, they did not
appear on the overlays generated by satid. (Did you not notice there
were no catalogued objects predicted on the satid images?)

Apparently Space-Track had some issues with their supply of data so I
do not know if this problem is related to the padding of NORAD catalog
numbers. If this remains then I will try to update the code.

For now, try to use the catalog from a few days ago.
