Deep Solar Minimum

Solar physicist Dean Pensell of the Goddard space Flight Centre of NASA, said, "We are experiencing a very deep solar minimum." Marshall Space Flight Center sunspot expert David Hathaway said, “This is the quietest sun we've seen in almost a century. Since the Space Age began in the 1950s, solar activity has been generally high. Five of the ten most intense solar cycles on record have occurred in the last 50 years. We're just not used to this kind of deep calm.”
