Receipt: # 2862-1 ----- Attempting Submission 2 (Wed Mar 23 14:27:35 GMT 2022) ----- We propose a detailed analysis of archived HST data from GO 13118, in order to study the ultra-faint particle trail from asteroid Bennu. The ejection of centimeter sized particles from Bennu was one of the major surprises from NASA's OSIRIS-REx mission and established this object as one of the Active Asteroids. The cause of particle ejection is not yet well established. Data obtained for another purpose in 2012 show evidence for an ultra-faint, narrow particle trail that likely corresponds to the summed emission from Bennu over months. We aim to optimally combine 80 images from GO 13118 and measure and model the trail to the full extent allowed by the data.
