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 1995, Irwin 1995) as well as Da Costa (1995) with the Anglo-Australian Telescope have confirmed its nature as remote globular cluster.
