Operating Spacecraft Around Comets: Evaluation of the Near-Nucleus Environment
C. M. Lisse, M. R. Combi, T. L. Farnham +9
We present a study of the current state of knowledge concerning spacecraft operations and potential hazards while operating near a comet nucleus. Starting from simple calculations…
Preview of Comet C/2021 A1 (Leonard) and Its Encounter with Venus
Qicheng Zhang, Quanzhi Ye, Shreyas Vissapragada +2
Long period comet C/2021 A1 (Leonard) will approach Venus to within 0.029 au on 2021 December 18 and may subsequently graze the planet with its dust trail less than two days later.…
Narrowband Observations of Comet 46P/Wirtanen During its Exceptional Apparition of 2018/19 II: Photometry, Jet Morphology, and Modeling Results
Matthew M. Knight, David G. Schleicher, Tony L. Farnham
We report on our extensive photometry and imaging of Comet 46P/Wirtanen during its 2018/19 apparition and use these data to constrain modeling of Wirtanen's activity. Narrowband ph…
Narrowband Observations of Comet 46P/Wirtanen During Its Exceptional Apparition of 2018/19 I: Apparent Rotation Period and Outbursts
Tony L. Farnham, Matthew M. Knight, David G. Schleicher +4
We obtained broadband and narrowband images of the hyperactive comet 46P/Wirtanen on 33~nights during its 2018/2019 apparition, when the comet made an historic close approach to th…
Recovery of Returning Halley-Type Comet 12P/Pons-Brooks With the Lowell Discovery Telescope
Quanzhi Ye, Tony L. Farnham, Matthew M. Knight +2
We report the recovery of returning Halley-type comet 12P/Pons-Brooks using the 4.3 m Lowell Discovery Telescope, at a heliocentric distance of 11.89 au. Comparative analysis with…
Detailed Characterization of Low Activity Comet 49P/Arend-Rigaux
Laurie E. U. Chu, Karen J. Meech, Tony L. Farnham +6
Comet 49P/Arend-Rigaux is a well known low-activity Jupiter Family comet. Despite the low activity, we have witnessed outgassing activity in 1992, 2004, and 2012. In 2012 a broad t…
