Lowell Putnam Trustee y remarks for 2013 are brief as MI only became Sole Trustee at the end of October. I would like to express my respect and admiration for the work of my father, Bill Putnam. As Sole Trustee for 26 years, his leadership and direction have raised the level of the observatory in so many ways. There is much challenge and opportunity ahead of us, but we have a strong base to grow on thanks to his efforts. We have a great staff, stronger participation by our Advisory Board and a growing group of supporters in the private sector. I am looking forward to 2014! ■

4 2013 Public Program Highlights

n 2013, Lowell welcomed 75,410 Iguests through the doors of the Steele Visitor Center for public and private programs. Regularly scheduled daytime activities included grounds tours, hands-on presentations, science demonstrations, and solar viewing. Nighttime programming included telescope viewing, SlipherVision (our 3D portable digital planetarium) presentations, and stargazing. The Starry Skies Shop stayed open during public and private functions, as did the exhibit hall. Samantha Christensen, Education Coordinator, directed efforts to build on the success of the first summer day camps developed in 2012. For 2013, camp leaders included Lowell educators, student interns from Mesa Community College, and local Newly appointed Outreach Manager Samantha Christensen helped teach Tykes teachers from the Flagstaff Unified Camp participants about balance using mobiles.
