AR2665: The Lonely Sunspot of Solar Minimum

A large, lone sunspot group marches across the solar disk over a period of almost two weeks. The spot group stands out during this minimum in solar activity. During the nearly two weeks of observations, a couple of instrument calibration maneuvers occurred. One happened on July 5, starting around 13:30UT (ending around 16:10UT), and another on July 12 around 15:10 UT (ending around 21:10UT).
