[Invitation to Harvard 25th service award]

An invitation that could not be accepted: I was relocating the Needham telescope to Oahu, Hawaii, as part of the global Radio Solar Telescope Network (RSTN), where it still operates at 240 MHz. The Harvard chair with monogram, celebrating my 25 years of service at Harvard, was waiting for me when I returned to Massachusetts from Hawaii. Credit: Photo courtesy of Doc Ewen.
