We report results of polarimetric observations of comet 21P/Giacobini-Zinner made at phase angles, {\alpha}=76-78 deg, between 10 and 17 of September 2018, and compare them with previous measurements.

While aperture-average polarimetry of 46P/Wirtanen reveals a nearly zero polarization PQ at the lowest phase angle {\alpha} = 18. 1 deg, simultaneous imaging polarimetry suggests that the negative polarization (PQ<0) arises in a region of within 5000 km of the nucleus, where the negative polarization could be as strong as PQ=-(1. 44 +/- 0. 15) percent.
