SDO – Comparing solar activity levels

sdo-comparing-solar-activity-levels

SDO released one-month videos of comparin the Sun's activity from periods about 2.5 years apart, with remarkable increase in solar activity seen. The video from October, 2010  sets it next to video from May, 2013 in the SDO's 171 Angstrom wavelength of extreme ultraviolet light. 

The number and intensity of active regions, seen as brighter areas and numerous loops above them, increased dramatically as the Sun is approaching its maximum level of activity which is expected to occur either late 2013 or early 2014.
