Other Canadian Comet Connections

  • Mike Boschat has reported over 50 comets observed in SOHO images, and was awarded the RASC's Ken Chilton prize for his accomplishments.
  • Art Fraser independently found Comet Kobayashi-Berger-Milon (1975h), before word arrived in Ottawa of the comet's discovery a week earlier. (Remember the days of snail-mail?)
  • Lillia Wilcox also found Comet Kobayashi-Berger-Milon (1975h). (?) (I need help with this story!)
  • Thanks to Gary W. Kronk for offering some tales of Canadian almost-discoveries.
  • Christopher Spratt independently discovered Comet Takamizawa (1994i) on May 8th, 1994.
