MPEC N12: COMET C/2019 K7 (Smith)


                           COMET C/2019 K7 (Smith)                             


     This object was reported as cometary by A. Heinze (T05) in discovery images obtained on 2019 May 30 UT:  "This object is extended relative to nearby field stars of similar brightness on all four images. We find the FWHM to be larger with at least 7 sigma significance relative to field stars, with an average FWHM excess amounting to 5.5 arcsec in quadrature.

A faint tail at least 20 arcseconds long extends toward the south-southeast, at a position angle of about 160 degrees." Other reports of cometary features are summarized below:
