Top space weather and astronomy events of 2011

But we also live within the “atmosphere” of the sun, and solar effects give rise to phenomena via the interplanetary magnetic field and the solar wind – space weather - which range from visually spectacular auroral displays to consequential (perhaps disastrous) disruptions in communications, power grids, satellite operations etc.(link)

Space-related events also make their mark on our collective experiences; for example, meteor showers, comets, solar/lunar eclipses, and manned and unmanned space exploration.

This selection of 2011’s top space weather and astronomy events doesn’t necessarily represent the most scientifically significant or historic set of a much larger set of possible choices. Rather, it is simply my personal list of highlights as an all-things space enthusiast - not far below enthusiasm for all-things (terrestrial) weather related.

Sun roars to life

Not withstanding some premature speculation that the sun might never “wake up” from the surprisingly quiescent and extended (5 year) period of the recent minima in the sun’s 11-year solar (sunspot) cycle, the sun roared into life in 2011. The past year was characterized by resurgence of sunspots, powerful solar flares and coronal mass ejections (CMEs), with the surge in solar activity expected to increase and eventually peak in 2013.

An especially unique view of an auroral display was provided by the surreal video of the southern lights, known as Aurora Australis, taken by the crew of the International Space Station on Sept. 17th.
