Abstract

This presentation describes efforts, using archival Hubble Space Telescope data, to determine if the Milky Way globular cluster NGC2419 has more than one stellar population. Preliminary, uncalibrated, color-magnitude diagrams in several color regimes are presented. The process of splitting its giant branch into a red half and blue half in the F390W-F625W color-magnitude plane is presented. Radial stellar density profiles are presented. A preliminary comparison of these profiles provides no evidence for multiple populations in this color-magnitude regime.
