June 21 marked both the summer and winter solstice, the longest or shortest day of the year for sunlight depending on which hemisphere you reside. Here are some glimpses of the power, beauty, and transforming presence of the sun, taken since the beginning of June. In this handout photo released by Nasa Earth Observatory on June 7, 2011 and taken from Nasa's Solar Dynamics Observatory, sunspot complex 1226-1227, shows the Sun unleashing an M-2 (medium-sized) solar flare, an S1-class radiation storm and a coronal mass ejection resulting in a large cloud of particles mushrooming up and falling back down giving the impression of covering an area of almost half the solar surface. An unusual solar flare observed by a NASA space observatory on June 7 could cause some disruptions to satellite communications and power on Earth over the next day or so, officials said. The potent blast from the Sun unleashed a firestorm of radiation on a level not witnessed since 2006, and will likely lead to moderate geomagnetic storm activity by Wednesday, according to the National Weather Service. Worshippers raise their hands to the Sun during the celebration of the Aymara New Year in Samaipata, 120 km west of Santa Cruz, Bolivia, on June 21.
