البقع الشمسية

Caption: تُبين هذه الصورة مجموعات من البقع الشمسية التي ظهرت على مدار تسعة أيام تقريبا بين شهري تموز واب سنة 2012. البقع الشمسية في هذه الصورة هي مصادر للتوهجات الشمسية والانبعاث الكتلي الإكليلي. في هذه الصورة على وجه الخصوص ، تقترب الشمس من الحد الأقصى لدورتها (الدورة الشمسية: هي التغير الدوري في النشاط الشمسي بما في ذلك التغيرات في مستويات الإشعاع الشمسي ، وكذلك تغيرات في مظهر الشمس ، مثل البقع الشمسية ووهج الشمس )، حيث نرى العديد من البقع تتشكل على امتداد خط الاستواء الشمسي. وتشاهد هذه البقع الشمسية والنشاط في النصف الجنوبي للشمس، قبل ذلك كان معظم النشاط في النصف الشمالي.
