Those living in lower latitudes might not have been aware of the recent solar and geomagnetic activities that triggered a spectacular aurora borealis the week of September 30. Two interplanetary shock waves, spawned by solar coronal mass ejections, swept past our planet September 28-29. Then on October 1, the interplanetary magnetic field around Earth turned south, causing geomagnetic storms to rage off-and-on for the next 48 hours. Luckily for those who missed the excitement, SpaceWeather,com features a page of beautiful, color .jpeg photographs of the auroras from such places as Finland, Quebec, and Alaska during September 29-October 3. Along with the images are the photographers' names, comments, and camera setting specifics.
