They do mention making observations on May 3-4, and I gather this continues in RC3 (a circular mapping orbit) that is above HAMO. I followed several status and journal links starting here:
http://dawn.jpl.nasa.gov/mission/status.html "Dawn will observe Ceres as it flies from 45 degrees to 35 degrees north latitude on May 3-4. Of course, the camera’s view will extend well north and south of the point immediately below it. (Imagine looking at a globe. Even though you are directly over one point, you can see a larger area.) The territory it will inspect will include those intriguing bright spots. The explorer will report back to Earth on May 4-5. It will perform the same observations between 5 degrees north and 5 degrees south on May 5-6 and transmit those findings on May 6-7. To complete its first global map, it will make another full set of measurements for a Cerean day as it glides between 35 degrees and 45 degrees south on May 7." -------------------- Steve [ my home page and planetary maps page ]
