Discovered in 1995 by Weinberger.
Barbara Wilson describes this one as:
Faint but clearly visible as a round evenly illuminated glow with no resolution
even at 450 power. [..] Inside of a sideways "V" shaped asterism of stars.
The Pyxis Globular Cluster was discovered by Ronald Weinberger in 1995 when
scanning various optical surveys (POSS, ESO/SERC) for new interesting objects.
He found this object to be detectible only in the infrared and classified it as
globular cluster candidate similar to AM4, or potentially
a nearby dwarf galaxy (Weinberger 1995).
Subsequent investigations by Demers, Irwin and Kunkel with the UK Schmidt
Telescope (Demers et.al. 1995,
Irwin et.al. 1995) as well as
Da Costa (1995) with the Anglo-Australian Telescope
have confirmed its nature as remote globular cluster.
