Solar

During March 7th 1970 solar eclipse on Nantucket island I flew our electrometer package using US Weather Bureau telemetry equipment (a WBRT) (I guess everyone at the UofMN was obligated to give mid-term exams that week so I got to do it). 

Clear day on Nantucket, eclipse beginning… WBRT telemetry receiver I was using on the tower in the background, amateur astronomers in the foreground. And yes, the birds sang at totality!
