Proposals for Global VLBI Network observing at centimeter wavelengths are handled by the NRAO. There are three Global sessions per year, with up to three weeks allowed per session. Plans for these sessions are posted online. Any proposal requesting NRAO antennas and antennas from two or more institutions affiliated with the EVN is a Global cm proposal. For all classes of proposals involving the EVN, only the on-line tool NorthStar should be used to prepare and submit proposals. Global cm VLBI scheduling occurs only on fixed dates.
