MGO first light

Fringes were successfully obtained between McDonald (MGO) and the two broadband antennas at MIT Haystack Observatory in Massachusetts, and the Goddard Geophysical and Astronomical Observatory (GGAO) in Maryland. All baselines, recording bands, and polarizations resulted in first fringes, confirming MGO’s interferometric detection and performance. Congratulations to the entire team!
