Parameter Symbol Value Units Sigma Reference Notes
comet total magnitude M1 15.0   1. 36 2 parameter fit from 127 observations, autocmod 2.9c
comet total magnitude slope K1 7.5   n/a 36 autocmod 2.9c
rotation period rot_per 21.04 h n/a LCDB (Rev. 2020-October); Warner et al., 2009 Result based on less than full coverage, so that the period may be wrong by 30 percent or so.
