Sandqvist objects


In 1976, as an adjunct to work measuring microwave signals of formaldehyde, Aage Sandqvist and Lukas Lindroos produced a catalogue of 42 "dark" nebulæ in the southern celestial hemisphere. They reported microwave observations on 27 of these objects, noting mean temperatures of 1.9 to 2.2 K and a variety of other microwave parameters.
In 1977 Sandqvist added a further 95 entries to the catalogue.

The positions and velocities of these objects were relates to larger scale galactic structures. Several of these objects are reported to have similar motions, implying an extended structure below current detection limits.
The second tranche of the collection re-started the numbering at 101 up to 195: Sandqvist 101, Sandqvist 102, etc.
None of these objects received further substantial attention .
