Report for 1/13/12

Over half of the Camilla Space Weather Project forecasters predicted a 60-80% chance of a solar event last week. Good job, forecasters! There were C-class solar flares on Jan. 9 and Jan. 12!

Last weekend, the Solar Dynamics Observatory (SDO) captured footage of sunspot AR1393 tripling in size in just over two days, growing to be about five times the width of Earth (see video)! Despite its size, this sunspot did not produce much activity. On the other hand, on Jan. 9, sunspot AR1395 caused a C-class solar flare when its magnetic field untwisted!

Sunspot AR1393 tripled in size last weekend!

A minor solar wind stream caused beautiful auroras around the Arctic Circle on Jan. 10. The Sun put on another show yesterday with an eruption on its far side, which caused a C-class flare (see image below). The active region that caused the eruption and flare will be turning toward Earth over the weekend; do you think it will cause any other events? Make your predictions here!

This active region produced a flare on Jan. 12 and will soon face Earth.
