Target OUMUAMUA: 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. We request that the contents of this proposal, specifically our discovery of non-gravitational acceleration, remain confidential to the extent allowed by STScI regulations. If such suggestions are permissible, we name Paul Chodas at JPL as a qualified reviewer. 513506558 Your proposal could not be saved. Submission aborted.

Which way home? Finding the origin of our Solar System's first interstellar visitor (Part II)cd We request four additional HST/WFC3/UVIS orbits of 1I/217 U1 ('Oumuamua), our Solar System's first interstellar visitor, in order to complete our DD program 15405. Our science goal is to obtain precise astrometry along an extended arc length in order to identify the region from which this object originated. Since the rotational light curve of 'Oumuamua shows variations of as much as 2.5 mag in brightness, a secure detection in the HST single exposures needed to maximize astrometric precision can only be assured in observations conducted at light curve maximum. However, we and other teams have recently determined that `Oumuamua is in a state of excited rotation and that, contrary to our intial expectations, we cannot predict the rotational phase in early January from existing data. We thus request four additional HST orbits that will allow us to sample `Oumuamua's light curve at multiple rotation phases, thereby ensuring that program 15405 will obtain a secure, final detection of our target that is crucial for this program to achieve its scientific objective. Four different visits to 1I/Oumuamua. All visits are identical: 5 long exposures of the target, with each image taken at a different dither location.
