About our Society

 The Astronomical Society of Eastern Missouri (ASEM) is an Astronomy club designed to put fun and passion into astronomy. We are based in St. Charles County, Missouri, and draw heavily from the St. Louis Metro area. Our members range in age from 8 to 85 and we all “love” Astronomy. We are very family friendly. We love to “share the view” through our public outreach and education programs, our meetings, our special interest groups (SIGs), our events, our relationships with other area clubs and national organizations, and sometimes just with each other while under the stars. While you are at this website, we trust you will get a feeling for our fun with, and passion about, Astronomy.
