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).

Videos of numerous AGU talks on Vesta from this past week are available online here (three separate sessions). I saw just a few of them in person - mainly about the large south polar crater.

After long hiatus (related to safe mode event one week ago) the simulator is up again! Yesterday, several short engine burns put Dawn on a 209 km average height but, interestingly, now eccentricity is increasing due to Vesta gravitational field:
The yellow curve is my rough attempt to interpolate trend through a sinusoid with 4.3 hours period and increasing amplitude (8 km/day) - anyway, remember that simulator is based on a nominal orbit design, not real time data!
