Tracking the Outbound Motion of Interstellar Comet 2I/Borisov.
Abstract
We are requesting 10 orbits to (1) perform high precision astrometry on the outbound orbit to model the non-gravitational acceleration and model the activity drivers; (2) confirm the rotation period detected in the previous HST program 16043, but with better contrast to get the nucleus axis ratio; (3) use the jets detected in the HST data to constrain the rotation pole; and (4) to observe the Earth's orbit plane crossing to analyze the activity profile of the large dust grains. For these observations we will use WFC3/UVIS imaging with F350LP passband. This request is to obtain data during 2020 March-September and the only way to secure this time is through a mid-cycle request.
