It's only 10 days now until the "Core" phase of the 2014 MU69 flyby begins! I thought it was time for a new thread. Carry on discussing distant observations of other KBO worlds in the KBO encounters thread, and use this one for MU69 until after the departure phase is officially over on 8 January.

I'll be posting a "What to Expect" article next week.

Could that explain the lack of light curve? (temporal resolution constraints)

I doubt it - some of the light curve observations probably include images taken with a short time interval between the images and probably also a variable interval.

But if it turns out that UT really us a quickly rotating object that must be good news since it means NH will be able to observe a bigger part of UT's surface.
