Moon, Earthshine
Posted: 7 June 2022
Friday, 3 June 2022, was cloudy. Cloudy skies continued until Monday, 6 June.
On Saturday, 4 June, I attended a four-hour online reunion of alumni and professors of the Indiana University Department of Astronomy. I was an astrophysics undergraduate student there 1966-70 and worked on the IU Asteroid Program during those four years. It was fun to see and hear everyone's stories about IU, the department, and how their careers have worked out. Although none of my classmates were there, it was nice to see and hear from Dr. Martin Burkhead, one of my professors.
