The target is extremely faint, and we need 5 orbits total to obtain a good detection of the morphology. We want the orbits to be consecutive to simplify the coaddition of images. Each of the orbits has exactly the same structure: 3 x 425s images at one location and 2 x 425s images at a dithered location. We want to observe within one month of the targets 2011 opposition, which is on 2011 June 6. SOLAR SYSTEM 0 false 0.0 0.0 false false false false SUPPORTED SOLAR SYSTEM MPEC F-16 solution. This must be updated prior to the detailed planning of the observations. I have used the "req ephemeris corr" special requirement, just in case the ephemeris accuracy is poorer than expected.
