Tracking of ephemeris objects will be possible in ALMA Cycle 2 as seen in Section 7 of the ALMA Cycle 2 Capabilities (or Section A.7 of the ALMA Cycle 2 Proposer's Guide):
"Sources can be designated by a fixed RA and Dec, or can include moving targets (including the planets, their moons, asteroids and comets). Observations of the Sun, however, are not supported in Cycle 2."
