Welcome to Observing Tool


This is the Gemini Observing Tool (OT), which is used to develop and plan Phase 2 Science Programs for the Gemini telescopes.

The Observing Tool is the work of the Gemini Observatory staff including Bryan Miller, Andrew Stephens, and the software engineers Arturo Nunez, Sebastian Raaphorst, Carlos Quiroz, Rob Norris, Shane Walker, and many former employees.
