From the Dawn mission update page:
May 15, 2015 - Dawn Spiraling Lower

Dawn is using its ion engine to maneuver to its second mapping orbit, which will be 2,700 miles (4,400 kilometers) high. It will reach that altitude in early June.

During the course of the day today, Dawn’s altitude will decrease from 5,500 miles (8,900 kilometers) to 4,800 miles (7,700 kilometers).

Tomorrow the spacecraft will pause ion-thrusting to take pictures of Ceres for navigation.
