Is there anything happening with the Sandusky High School observatory?
Quite the contrary, Jon. The Sidney Frohman Planetarium is still in use, and serves students and adults for a variety of astronomy programs. Especially popular are the annual "A Christmas Story" programs, which are typically scheduled on weekends in December. You can contact the planetarium director, Lois Wolf, at 419-984-1155 to schedule a time to visit.
