PI: Dr. Mark R. Showalter SETI Institute Y CoI: Prof. Imke de Pater University of California - Berkeley N CoI: Dr. Jack J. Lissauer NASA Ames Research Center N ------------------------------------------------------------------------------------ Abstract This program will address three key science goals related to the rings and inner moons of Neptune. (1) We will recover S/2004 N 1, Neptune's 14th moon, whose discovery was announced by STScI in 2013. This 8-10 km moon orbits between the much larger moons Larissa and Proteus, raising questions about its origin and orbital stability. Measurements from Cycle 23 will supplement the only existing measurements from 2004-2005 and 2009, giving us necessary confirmation of the discovery and providing much stricter constraints on the moon's orbital elements. (2) We will locate Naiad, the innermost known moon, whose orbital position appears to have jumped by 81 degrees in orbital longitude between 2002 and 2004. New measurements will determine whether (a) the 2002 measurements were erroneous, or (b) the moon follows a highly perturbed orbit. If the latter, our measurements will place strong constraints on the nature of these unknown perturbations. (3) We will revisit the arc system embedded in the Adams ring of Neptune. The leading arcs have disappeared since the 1989 Voyager flyby; the trailing arcs have been more stable, although they appear to be fading slowly. We will investigate this unexplained trend, and also seek out evidence for other subtle changes in the rings, by obtaining the first rotationally complete, visual-band profile of the ring-arcs since 1989. ------------------------------------------------------------------------------------ Observations Description ------------------------ Five single-orbit visits to Neptune are spaced out over time to obtain complete orbital coverage of Naiad, S/2004 N 1, and the Adams ring. Each visit contains eleven long exposures through filter F350LP to detect the small moons and faint rings. A single, unsaturated exposure of Neptune is included in each visit for geometric and photometric reference. A dither step is inserted half-way through each orbit so that the influence of hot pixels can be suppressed. All visits are oriented such that Neptune's pole is roughly aligned with the Y-axis of the CCD. This is necessary so that the saturation bloom is separated from the rings and moons, which extend primarily to the right and left. However, we use a slightly different roll angle for each visit because this will help us to separate out the rings from the pattern of glare surrounding Neptune. Based on SAA constraints, four visits have been modified to be split across consecutive SAA-affected orbits. ------------------------------------------------------------------------------------ 14217( 4) - 20-Jul-2016 14:09:23 - [ 2] TARGET LIST Solar System Targets ------------------------------------------------------------------------------------------------------------------------------------ TARGET NUMBER: 1 TARGET NAME: NEPTUNE ------------------------------------------------------------------------------------------------------------------------------------ TARGET DESCRIPTION: PLANET Planet Neptune ------------------------------------------------------------------------------------------------------------------------------------ TARGET POSITION LEVEL 1 TARGET POSITION LEVEL 2 STD=NEPTUNE ------------------------------------------------------------------------------------------------------------------------------------ TARGET POSITION LEVEL 3 WINDOWS NOT ECL P PARTIAL OF NEPTUNE BY TRITON FROM EARTH ------------------------------------------------------------------------------------------------------------------------------------ DATA COMMENTS V = 7.9 +/- 0.1 Ephemeris Center: EARTH ------------------------------------------------------------------------------------------------------------------------------------ 14217( 4) - 20-Jul-2016 14:09:23 - [ 3] Visit: 01 Visit Requirements: ORIENT 271D TO 273 D; ORIENT 91D TO 93 D; BETWEEN 2016.244:06:00:00 AND 2016.244:09:30:00 On Hold Comments: Additional Comments: Neptune oriented with its pole oriented 9 degrees counterclockwise from the Y-axis. This visit is split across two consecutive SAA-affected orbits. A dither shift of 5 pixels along the X and Y axes occurs half-way through the visit. Time intervals between HST orbits have been selected to sample Naiad, S/20014 N 1 and the Adams ring at a full range of orbital longitudes. This visit is timed to place S/20014 N 1 and the arcs on the east side of Neptune.
