The Commission 46 Program Group Exchange of Astronomers (PG-EA) provides travel grants to astronomers and advanced students for research or study trips of at least three months duration. Highest priority is given to applicants from developing countries whose visits will benefit them, their institution and country, and the institution visited. This program, if used strategically, has the potential to support other Commission 46 programs such as Teaching for Astronomical Development (PG-TAD) and World Wide Development of Astronomy (PG-WWDA). Complete information about the program, and the application procedure, can be found at <physics.open.ac.uk/IAU46/travel.html>.
