This particular picture was taken by Vasiliy Rumyantsev in Crimea. This is the most complicated picture captured by this photographer. In order to capture an analemma, each picture must be taken from the same location at the same time for a year – this is no easy task. Between August 30, 1998 and August 19, 1999. http://www.fromquarkstoquasars.com/solar-analemma/
Solar Tsunami Used To Measure Sun’s Magnetic Field A solar tsunami observed by NASA's Solar Dynamics Observatory (SDO) and the Japanese Hinode spacecraft has been used to provide the first accurate estimates of the Sun's magnetic field. Solar tsunamis are produced by enormous explosions in the Sun's atmosphere called coronal mass ejections (CMEs). As the CME travels out into space, the tsunami travels across the Sun at speeds of up to 1000 kilometres per second.
