I think is time to start this new topic, now that Dawn is more than half-way in the transition from HAMO to LAMO (as showed in the plot below).

The latest four images were posted on the same day... I check every day, believe me. We had a minibreak. But these are spectacular!

Now that we have an improved simulator (better Vesta digital model and, especially, more frequent screen updates) I am frequently monitoring the simulated height of the probe; in the last 24 hours, engines were off but orbit isn't completely stable:
The interpolated sinusoidal curve correspond to a 5.1 hours average period between 235 and 285 km height. The reason of slight phase/amplitude variations sould be the irregular gravity field of Vesta. In fact, as explained in the last Mission Status, the purpose of these thrust stops is a natural or passive orbit adjustment (especially the orientation). Edit: slightly modified previous text and updated plot (no orbit decay) -------------------- I always think before posting! - Marco -
