Target 2014MU69: There is no need or capability to test the scheduling of observations of moving targets in Phase I. This warning will go away the next time the proposal is loaded.0Assigned ID: 678
----- Attempting Submission 1 (Fri Apr 08 18:44:05 GMT 2016) -----Visit planner won't run due to having a moving target for the proposal. There is only one useful keyword. The list
of solar system keywords is rarely, if ever, sufficient to provide three for any such proposal.This is now a complete version, ready for scheduling and implementation.-208514851----- Attempting Submission 1 (Fri Jul 01 12:32:38 GMT 2016) -----

----- Attempting Submission 3 (Wed Aug 09 20:44:33 GMT 2017) -----Astrometry of 2014MU69 for New Horizons encounterWe propose 12 orbits of time to make high-precision astrometric measurments of the New Horizons extended
mission target, (486958) 2014MU69. These observations are in direct support of the navigation of New Horizons
leading up to its encounter in Jan 2019. These visits represent an optimized plan for improved orbit estimates that will
complete as the target becomes directly observable by New Horizons. This astrometry is a key element leading
up to a close investigation of a Cold-Classical Kuiper Belt Object, one of the most primitive members of our solar
system.These observations will use the full field of WFC3/UVIS due to its improved broadband PSF and detector sensitivity compared to ACS. This was the HST instrument used to successfully to detect 2014MU69 and our other potential KBO targets in our 2014 search campaign. We are using the F350LP filter for its sensitivity and image quality as well as consistency with the prior observations. Our observing strategy is based on the successful strategy developed for our 2014-2016 HST KBO search and followup campaigns. For each HST orbit we will use WFC3 with the F350LP filter to obtain five 370 second exposures. We will track on the known motion of 2014MU69, which results in trailing of stars, but does not prevent their removal to provide robust detections in single orbits as shown. The formal uncertainty of the position is less than 1 pixel for the
entire campaign. Thus, the target can easily be placed near the center of WFC3/UVIS2, and very bright stars can be avoided by adjusting the timing of the observations as necessary. Once preliminary observing windows are available we need to examine the background star field for contamination and final scheduling to avoid field stars. We require acquisition of the full WFC3 field for precise astrometric solutions. The visit
timing is designed to get broad time coverage for the orbit estimation needed for New Horizons navigation support. The one week period is chosen to provide ample scheduling flexibility and could be shifted by another day or two if needed. The timing of these weeks is controlled by avoiding the time around quadrature when the sky-plane velocity is below 1 arcsec/hour and the need to get the visits spread out in time throughout the annual observing window.Solar System3falsefalsefalsefalsefalsefalsefalseSUPPORTEDSOLAR SYSTEMASTEROIDKuiper-Belt ObjectTYPE=ASTEROID,A=44.424476580257,E=0.038363213356,I=2.453094139706,O=158.936790467222,W=176.622025091325,M=312.385824919521,EQUINOX=J2000,EPOCH=15-OCT-2017:00:00:00,EpochTimeScale=UTCEARTHSOLAR SYSTEMASTEROIDKuiper-Belt ObjectTYPE=ASTEROID,A=44.473102812902,E=0.039259517927,I=2.452733880004,O=158.948389200514,W=175.695512739008,M=313.833282669452,EQUINOX=J2000,EPOCH=15-MAR-2018:00:00:00,EpochTimeScale=UTCEARTHSOLAR SYSTEMASTEROIDKuiper-Belt ObjectTYPE=ASTEROID,A=44.492574897611,E=0.039629508082,I=2.452583078982,O=158.953189784881,W=175.350376717272,M=314.389538439094,EQUINOX=J2000,EPOCH=15-MAY-2018:00:00:00,EpochTimeScale=UTCEARTHSOLAR SYSTEMASTEROIDKuiper-Belt ObjectTYPE=ASTEROID,A=44.513501621971,E=0.040055519605,I=2.452413335340,O=158.958551873314,W=175.026266510289,M=314.929209695644,EQUINOX=J2000,EPOCH=15-JUL-2018:00:00:00,EpochTimeScale=UTCEARTHSOLAR SYSTEMASTEROIDKuiper-Belt ObjectTYPE=ASTEROID,A=44.522607562638,E=0.040269637522,I=2.452265958242,O=158.963182412558,W=174.926199040395,M=315.140003030700,EQUINOX=J2000,EPOCH=15-AUG-2018:00:00:00,EpochTimeScale=UTCEARTHWFC3/UVISImagingNoNoF350LPWFC3/UVISImagingNoNoF350LPWFC3/UVISImagingNoNoF350LPWFC3/UVISImagingNoNoF350LPWFC3/UVISImagingNoNoF350LPWFC3/UVISImagingNoNoF350LPWFC3/UVISImagingNoNoF350LPWFC3/UVISImagingNoNoF350LPWFC3/UVISImagingNoNoF350LPWFC3/UVISImagingNoNoF350LPWFC3/UVISImagingNoNoF350LPWFC3/UVISImagingNoNoF350LPCELESTIALOTHER.030Objects will naturally dither themselves in a predominantly east-west direction.
This dither pattern uses offsets perpendicular to the mean motion of the objects
with a two-level pattern so that the dither cannot lead to a false detection with
coherent motion. The overall pattern is six positions with 0.75 pixel spacing.LINEfalsetrue50LINE1falseUsing ephemeris for target 15158-07-486958-Aephemeris data for target 15158-07-486958-A does not cover planning interval.
