Warning is for an unused pattern and/or visits 11-12 which are on hold Recovery and Orbit of a Satellite of the Trojan Asteroid Eurybates - a Lucy Mission Target A deep search for satellites around Jupiter Trojan asteroids that are targets of NASA's Lucy mission has yielded the detection of a small satellite with d<~1km orbiting Eurybates. Observations on 12 and 14 September 2018 show a V~26.77 mag object at a projected distance of 1928 km from Eurybates that is moving at a rate consistent with that of a bound satellite. The Lucy spacecraft is planned to fly within this distance to a close approach of 1000+/-75 km. Thus, it is of critical importance to the mission to recover the satellite and constrain the orbit in order to evaluate the impact on the design of targeting, flyby, and science sequences, data volume, and other potential effects. We are requesting immediate observations prior to 11 January 2020 for recovery and initial orbit characterization with more detailed orbit determination observations during the next very favorable opposition starting in September 2020. We have three single-orbit visits to observe Eurybates to attempt recovery of a satellite with an unknown orbit. The potential satellite was observed on Sep 12 and 14, 2018 at a projected distance of ~1900 km (0.58 arcsec). Because the orbit period is not known and the satellite is ~9.5 mags fainter than Eurybates, it will be difficult or impossible to detect when it is closer than ~0.4 arcsec from the primary. For this reason we want to spread the three visits out in the interval from the first visit (somewhere between Dec. 9 but before Dec 22, depending on calendars) and the last day of HST visibility on Jan 11. That window is how we arrived at the AFTER BY 10-17 day requirement. We request the first visit be scheduled as soon as possible to allow the longest window in which to fit the three visits. The very latest scheduling for the first visit is Dec 21, but sooner is better. A longer window increases the chances of timing at least one visit when the satellite is far enough from the much brighter primary to be detectable. Earlier also is better in terms of angular scale because the geocentric distance to the target is increasing by about 2% per week. Exposure times can be shortened as needed to schedule. A 10 sec decrement in the six long exposures saves 60 sec overall. If more than 20 sec per exposure needs to be cut, please consult with us first. The proposal team consists of members of the Lucy mission team who have been working on the Lucy mission for more than five years. Levison and Olkin are the PI and DPI of the Lucy mission and have extensive and complete knowledge of mission requirements and the spacecraft, instrument, and operations capabilities necessary for mission success. Noll, Weaver, Brown, Buie, Grundy, Spencer, and Porter have extensive experience with planning and analyzing HST observations of small solar system bodies and an extensive publication record using HST data. Statler is Program Scientist for Lucy and intimately familiar with the mission's science requirements, as well as experienced with asteroid photometry.
