TRAPPIST comet production rates: 88/Howell, C/2020 M3 (ATLAS), C/2020 S3 (Erasmus), 156P/Russell-LINEAR

Abstract

E. Jehin, Y. Moulane, J. Manfroid, F. Pozuelos, D. Hutsemekers (STAR Institute, University of Liege) report that they obtained from TRAPPIST-South (I40, Chile) and TRAPPIST-North (Z53, Morocco) 0.6-m robotic telescopes (Jehin el al. 2011) observations using HB narrowband filters (Farnham et al. 2000) for the following comets and computed preliminary production rates at 10.000 km using a Haser Model (Vp=Vd=1km/s) (Haser 1957).
