These objects have spectra typical of old stellar systems, but are unresolved in ground- based imaging. They are all at least 10 times more luminous than any Galactic globular clusters, but fainter than any known compact dwarf galaxies. They may be a new class of intermediate object, neither globular clusters nor dwarf galaxies but something in between. The observations completed nominally. There were no reported problems.
All exposures are internals.
The observations completed with no reported problems. A wavelength calibration image was also taken. The observations were executed as scheduled, and no anomalies were noted. The largest impediment to our understanding of planetary nebulae is the lack of reliable distances. The observations were executed as scheduled, and no anomalies were noted.
