Discovery of Haumea

On July 29, 2005, Ortiz announced the discovery of Haumea, provisional designation 2003 EL61, one of the few officially recognized dwarf planets of the Solar System. This led to a controversy over who to credit for the discovery: Michael E. Brown and his team at Caltech had also been observing Haumea, and for a longer period of time than Ortiz, but had withheld publication pending securing its orbital parameters. Brown initially supported Ortiz and his team being given credit for the discovery, but withdrew that support when it turned out that Ortiz had accessed Brown's public observation logs and research just before announcing the discovery. Additional information was provided that showed that Ortiz and his team only started researching this object after looking at Brown's Caltech telescope files. After ignoring requests from Brown and only after a complaint was filed with the International Astronomical Union (IAU), did Ortiz finally respond to the accusation. Ortiz maintained that he only did so to see if this was the same object that his team had been tracking. The IAU did not award credit to either party, but listed the Spanish observatory as the place of discovery, and accepted the Caltech suggested name of Haumea rather than Ortiz's Ataecina. Ortiz is mentioned in Brown's memoir How I Killed Pluto and Why It Had It Coming.
