( Second ) March NSA Club Meeting

  • Arlington Heights Memorial Library 500 North Dunton Avenue Arlington Heights, IL, 60004 United States (map)

Comets have fascinated people since ancient times, when they were often seen as portents of significant events.  We know better in our scientific age, but they still engage us.  NSA member Todd Augustyniak will give a brief history of comets, discuss their composition, and review their orbital mechanics.  He will also provide tips for observation and photography of some of the brighter comets of 2018.
